Design Considerations for Analog-Input Class-D Speaker Amplifiers

Output Filter Design

To Know More

• Most of TI’s Class-D amplifiers operate without a filter when speaker wires are less than 10cm.

For a complete list of Analog-Input Class-D Speaker Amplifiers, see selection guide on page 22. For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio

• When speaker wires are long, place a second-order low-pass (LC) filter as close as possible to the amplifier’s output pins. • The filter must be designed specifically for the speaker impedance because the load resistance affects the filter’s quality factor, or “Q.”

Output Power per Channel

• A ferrite bead may also eliminate very high-frequency interference.

• Maximum power is decided primarily by power supply (output voltage and current) and speaker impedance.

PCB Layout • Place decoupling capacitors and output filters as close as possible to the amplifier IC.

• Efficiency of Class-D amplifiers is typically between 80% and 90%, which reduces demands on the power supply design.

• When using a ferrite bead filter place the LC filter closest to the IC.

• The maximum input signal level dictates the required power amplifier gain to achieve the desired output power.

• Always connect the PowerPAD™ connection to the power ground.

• For best noise performance, the gain should be as low as possible.

• When the PowerPAD package serves as a central “star” ground for amplifier systems, use only a single point of connection for the analog ground to the power ground.

Heat

To Know More

• Driving 2W per channel in stereo systems generates 6W of heat with an efficiency of ~40%.

For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio

Output Power per Channel • After determining the number of speakers in a system, specify the output power for each channel. • Maximum power is decided primarily by: • Power supply (output voltage and current) • The amplifier’s maximum output voltage • Speaker impedance • Maximum efficiency is ~40% with Class-AB amplifiers. • The power supply must provide continuous current to support the desired maximum power. • The maximum input signal level dictates the required power amplifier gain to achieve the desired output power. • For best noise performance, the gain should be as low as possible.

• TI’s Class-AB speaker amplifiers feature the PowerPAD™ package, using a PCB as a heatsink. • See the application brief “PowerPAD™ Made Easy” for package layout and other design considerations at: http://focus.ti.com/lit/an/slma004b/slma004b.pdf Features • Class-AB amplifiers offer several different ways to control the gain or volume: • External resistors (similar to traditional op-amp circuits) • Integrated gain-setting resistors • DC volume control • I2C volume control • Most of TI’s portfolio provides the three latter control options. • When a headphone drive is part of the design, most Class-AB amplifiers with TTL-input pins can change outputs from bridge-tied load (BTL) to single-ended (SE) configurations, eliminating the need for an additional amplifier.

Design Considerations for Headphone Amplifiers

➔

• TI counters this high-pass filter issue with capless and DirectPath™ technologies. • Capless creates a virtual ground (VDD/2) for the headphone connector. Both amplifier outputs then have a VDD/2 bias, ensuring that no DC passes through a speaker. • DirectPath-enabled devices include an internal charge pump which creates a negative power rail inside the device. With this design, an amplifier can be powered by a bipolar supply and have an output biased to ground.

To Know More

For a complete list of Headphone Amplifiers, see selection guide on page 23. For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio

Issues to Consider When Using Single-Ended Power Supplies • Many amplifiers work at single +3.3-V or +5-V supplies.

Headphone Impedance and Power

• These power supplies require a DC-biased amplifier output to ensure undistorted output.

• Headphone impedances can vary greatly, from 16Ω to 600Ω. • When choosing an amplifier, always ensure that it can handle the power at the specified voltage range and headphone impedance.

• Placing DC-blocking capacitors between the speaker and the amplifier causes a high-pass filter and equates to poor bass response.

To Know More

• The size and expense of DC-blocking capacitors has led to capless methods to implement output.

For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio

Radio Emission Interference in Notebook PCs

• VBias on ground sleeve removes the caps, but can inject a hum or damage the amplifier if ground loopback occurs with an external device.

• RF emissions from mobile data add-in cards, 802.11 and Bluetooth® radios can create noise problems for amplifiers.

• DirectPath™ solutions eliminate ground loopback and improve bass response.

• It can be particularly problematic if the amplifiers, codecs or speakers are separated from each other by industrial or board design requirements. • For additional design flexibility, use devices with differential inputs, which provide significantly better noise immunity.

• At a given gain, microphone preamplifiers exhibit a certain amount of input noise that is amplified together with the audio source. • Ideally, microphone preamplifiers will have low EIN values to ensure that only the audio source is amplified instead of the noise. Outputs: Differential vs. Single-Ended

Control Methods: Analog vs. Digital • Analog control microphone preamplifiers typically use a variable resistor on a product’s front panel that can be changed during performance. • Digitally controlled microphones are remotely controllable and have easily recallable settings, offering significant advantages when compared to their analog control counterparts. • In the live sound and recording industry, digitally controlled microphones allow signals to be preamplified and converted closer to the source rather than sending tiny µV signals across meters of cable.

• Inside a product, a single-ended output is sufficient to process signals needing further processing. • Many high-performance ADCs require differential inputs. If the amplified differential microphone signal is taken directly to an ADC, a differential output will give an additional 6dB of dynamic range. • Differential outputs from a microphone preamplifier will help ensure that the differential input on the receiver will reject any common-mode interference induced on the cable by cancelling out the common noise on both connections.

Audio Amplifiers Balanced-Line I/O for Professional Audio Applications

To Know More

• By having equal impedance to ground on both conductors, balanced-line I/O offers two advantages: • The noise induced is near equal and should be cancelled by a balanced-line receiver as common-mode noise • Having inverted signals on both conductors also adds another 6dB to the dynamic range for the same supply voltage

Driving 2VRMS for Audio/Visual Applications • Almost all audio coming into a television has a ground-centered 2VRMS output.

Overall Op Amps

• Most audio DACs have a sub-4VPP with a DC bias ~2.5V.

• When selecting an op amp, investigate its input stage.

• The traditional solution for generating a ground-centered 2VRMS output is to run an output op amp stage from a higher voltage bipolar power supply (±12V).

• FET-based op amps usually have a very high input impedance.

• This solution adds complexity, especially if the rest of the devices are using only 3.3V or 5V.

• BJT (bipolar)-based op amps exhibit lower input impedance and offer lower input noise.

• TI’s DRV60x family integrates the amplifier and charge pump to create positive and negative rails for clean, ground-centered 2VRMS output.

• Bipolar op amps are ideal input devices for low-impedance output sources requiring low noise amplification.

• FET-input devices are ideal when the output impedance of the source isn't easily known, such as with a musical instrument.

Design Considerations for Volume Controls Maintenance of Dynamic Range

To Know More

For a complete list of Volume Controls, see selection guide on page 24.

• Multiplying the DAC’s digital value by < 1 is an acceptable way to control volume for many applications, using fewer bits to represent the signal while the noise level remains the same.

For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio

• Combining fewer bits to represent a signal with a fixed-noise level will increasingly reduce the dynamic range as the volume changes. • By changing the volume in the analog domain while under digital control, the DAC’s inherent noise will be attenuated along with the audio.

Supply Voltage: Signal Swing • DAC outputs typically have a swing of around 3VPP. • Broadcast signal swings can easily be 25VPP or higher. • Knowledge of the signal amplitude that will be attenuated is critical when choosing digitally controlled analog volume controls. • For controlling DAC output, ±5-V devices are more than adequate to provide 10-VPP headroom for a signal that, at maximum, will be below 5VPP.

Audio Converters Processing Allocation and Software Reusability

To Know More

Reducing Noise on Microphone Inputs • Microphone signals are susceptible to noise injection due to the low peak-to-peak range of 10mV. • Placing the codec or ADC close to the microphone often conflicts with user preference, industrial design or mechanical design requirements. • Look for devices which can work with digital microphones or have differential inputs, both of which provide significantly better noise immunity.

Simultaneously Handling Multiple Audio Sources • Designers of handheld consumer electronics don’t have the option of focusing on a single sample rate or audio signal source. With multiple functions come different radios and sampling rates. Look for codecs with: • Multiple independent analog and digital interfaces • The ability to independently sample and process these two signals

To Know More

• TI's highly integrated range of consumer converters support complex signal-chain designs.

For a complete list of Home and Professional Audio Converters, see selection guide on pages 25 and 26.

• Integrating functionality such as multiplexers, programmable gain and S/PDIF transmitters into a single package reduces cost, design complexity and time to market.

For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio

• Home and professional audio converter performance is measured in dynamic range, not bit depth. • A 24-bit converter describes its output format, not its quality. Therefore, many of the least significant bits in a 24-bit audio word may be noise. • At its peak, a standard CD has 98.08-dB (16 bit) dynamic range.

• Converters can be controlled in many different ways; many simply by tying pins high and low. • A small micro, SPI shift register or I2C expander can allow control from a remote source. • For products with increased integration, control is typically through either SPI or I2C. • When choosing converters or codecs, confirm both the control method and the existence of additional I/O (GPIO, SPI or I2C) for the main processor to support the device.

• In professional environments, a converter may have a dynamic range of up to 132dB.

For a complete list of Audio Converters with Integrated Touch-Screen Controller, see selection guide on page 27. For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio

• TSCs detect contact and then require the host to handle as many as 40 to 50 register read/write cycles. • These requirements create additional interrupts and processing cycles, which reduces processing efficiency. • To reduce this load on the host, look for “smart” TSCs with the ability to generate coordinates with minimal interaction from the host.

Supporting Varying Mechanical System Designs • The preferred solution with a single integrated TSC + audio device or a discrete TSC and audio codec may depend on whether a handheld device is built on: • A single-board platform, such as a candy bar • A PDA form factor • An in-dual board platform like a flip phone • TI offers a wide selection of stand-alone TSCs and audio codecs as well as integrated TSC + audio devices for all types of system designs.

Design Considerations for S/PDIF Interface and Sample Rate Converters ➔

Jitter Sensitivity

To Know More

• Jitter can be a major problem in a digital audio system.

For a complete list of S/PDIF Interface and Sample Rate Converters, see selection guide on page 28.

• Jitter is introduced when digital audio clocks are generated or regenerated from a different clock source and by using interconnects that have significant parasitic impedance (capacitance, inductance etc.).

Sample Rate Converters (SRCs)

• Jitter in digital audio systems moves the sampling instant back and forth in time, adding noticeable distortion in high frequencies.

• SRCs create sample rate and phase-independent interfaces between fixed-rate digital processors and the outside world.

• For the smallest adverse impact on the audio content, choose S/PDIF receivers with low jitter.

• SRCs can serve as “jitter cleaners,” lowering the amount of jitter on incoming data streams.

System Partitioning • System partitioning options include discrete transmitters, receivers and stand-alone SRCs, as well as combinations of transceivers and SRCs.

• SRCs allow similar phase-independent sample rates to be brought into systems without the need for time alignment/word clock distribution.

• Flexible functionality allows end products to be either: • A clock master (and SRC from the outside to its internal process clock) • A slave to an external clock (and SRC the output to the new clock rate)

• The signal switch is controlled by the output of a digital source in most applications. • The control signal levels, VIH and VIL, must be compatible with the digital source to ensure proper operation of the switch. On-State Resistance (ron) Tradeoffs • ron contributes to signal loss and degradation.

V+ and the Max Analog Signal Amplitude • V+ determines the analog signal amplitude that can be passed without clipping for noncharge-pump switches. • The gate(s) of the pass transistors must be biased relative to the minimum and maximum values of the expected input voltage range. • Some switches allow for biasing from two supplies, making it easy to pass both positive and negative signals. • Switches with integrated charge pumps can elevate the gate voltage above V+ (at the expense of larger I+) and thus pass signals of a magnitude greater than V+.

• Non-charge-pump switches achieve low ron with large pass transistors. • Leads to larger die sizes and increased channel capacitance (CI/O) • Limits the frequency response of the switch • Switches using charge-pump technology can achieve low ron and CI/O but require significantly higher I+. On-State Resistance Flatness [ron(flat)] • On-state resistance flatness specifies the minimum and maximum value of ron over the specified range of conditions. • Conditions may include changes in temperature or supply voltage.
