TAS5710PHP - 20W Stereo Class-D Amplifier | Texas Instruments
料号： TAS5710PHP ✓ 量产中TAS5710PHP 概述
A Class-D audio amplifier is a switching power amplifier that uses pulse-width modulation to deliver speaker power efficiently. Compared with a linear audio amplifier, this approach reduces the amount of power dissipated as heat in the output stage. A digital-input device accepts encoded audio data rather than an analog line-level signal, allowing software-defined volume, equalization, and dynamic-range-control functions to be applied before the signal reaches the power-output stage.
The TAS5710PHP combines two stereo output channels, digital signal processing, and closed-loop output feedback in one package. Its identified 20 W output capability is suitable for compact consumer-audio equipment where space and power efficiency matter. The integrated equalization function can shape speaker response, while the 2-band DRC can reduce unwanted level variation. Exact processing coefficients, gain settings, output-power conditions, and thermal limits depend on the manufacturer configuration and test conditions.
The digital input architecture makes the amplifier suitable for systems in which a host processor or digital audio codec supplies I2S-compatible data. Designers can centralize mixing, source selection, volume control, and tone processing in software, while the TAS5710PHP converts the digital stream into a bridge-tied Class-D speaker drive. The closed-loop topology is intended to improve output behavior by using feedback to correct the delivered bridge-tied voltage.
Typical uses include powered speakers, soundbars, compact stereo systems, wireless speakers, displays, and consumer audio products with digital audio sources. The 48-pin HTQFP package offers many connections for power, ground, digital audio, configuration, feedback, and output stages, but the complete exposed-pad land pattern and thermal-management requirements must be followed exactly.
Layout is as important as the logical signal path. Place the decoupling capacitors close to their associated supply pins, provide a low-impedance ground return for the power stage, and route the sensitive digital, clock, and feedback connections away from switching-node currents. The exposed thermal pad must be connected to the ground plane with adequate copper and vias; otherwise the 20 W class can create a substantial thermal burden even though the amplifier is electrically efficient.
This page consolidates the verified manufacturer and distributor information, distinguishes documented capabilities from unspecified parameters, and provides application and design guidance that should be checked against the complete manufacturer datasheet before schematic capture or PCB release.

典型应用
TAS5710PHP 适用于 6 应用s: Compact Powered Stereo Speaker, Wireless Speaker, Soundbar Speaker Module, Digital Audio Display, Smart Home Audio Node, Compact Audio System.
Compact Powered Stereo Speaker
The TAS5710PHP fits a compact powered speaker because it combines a documented 20 W stereo output capability with digital input, closed-loop feedback, equalization, and 2-band DRC in a 48-pin 7 x 7 mm HTQFP package. A host processor can send the digital audio stream and adjust processing without requiring separate analog preamplifier stages. The 10 V to 26 V supply range also accommodates common higher-voltage portable audio rails. Before release, verify the speaker impedance, continuous and peak output-power conditions, thermal rise, and whether the selected output-filter network is required. The exposed thermal pad should be connected to a substantial ground plane with multiple thermal vias so the Class-D output stage can dissipate its losses effectively.
推荐
Wireless Speaker
A wireless speaker can use the TAS5710PHP when the wireless audio platform ultimately presents a digital stream to the amplifier. The part's documented 20 W stereo capability supports two bridge-tied speaker outputs, while integrated equalization and 2-band DRC provide useful speaker-response and level-control functions close to the power stage. Digital control can also reduce the need for discrete preamplifier and volume-control circuitry. The design must confirm the required digital-audio format, clocking, and configuration protocol, plus the input-voltage range and load supported by the wireless module. Thermal layout is especially important because a compact enclosure limits heat dissipation even though Class-D operation is more efficient than linear amplification.
推荐
Soundbar Speaker Module
The TAS5710PHP is suitable for an individual soundbar speaker module where two amplified channels, digital source control, and local speaker shaping are required. Its documented 20 W stereo rating, equalization, and 2-band DRC allow a system integrator to tune output response and control level variation within the amplifier. The digital interface supports centralized volume and source management, while closed-loop feedback helps the amplifier regulate its bridge-tied outputs. Soundbar implementations must still account for enclosure acoustics, thermal dissipation, EMI from Class-D switching nodes, and the exact speaker load. Validate the system's maximum output level against both the amplifier's specified test conditions and the thermal limits of the complete enclosure.
推荐
Digital Audio Display
The TAS5710PHP can serve as the speaker amplifier in a display or monitor when the platform already transports audio digitally. Its 20 W stereo output capability covers compact left-right speaker pairs, while integrated equalization can compensate for speaker and enclosure response and 2-band DRC can manage program-level differences. Integrating the processing in the amplifier also permits system-level volume and tone management through the digital control path. The implementation should confirm whether the display's audio source supports the amplifier's required digital interface and whether the system needs a specific filter or protection scheme. Place the amplifier power stage away from sensitive display circuitry and provide adequate exposed-pad cooling in the constrained display enclosure.
推荐
Smart Home Audio Node
The TAS5710PHP is appropriate for a smart-home audio node that receives a digital audio stream from a network or local processor and drives a pair of compact speakers. The device's documented 10 V to 26 V supply range supports design flexibility, while equalization and 2-band DRC provide system-level control of speaker response and level consistency. Its 48-pin HTQFP package is well suited to multilayer consumer-electronics boards where component density matters. Engineering work should verify digital clocking, configuration persistence, startup behavior, and the precise interpretation of the 20 W rating. Low-power standby requirements may also require checking omitted current specifications against the complete manufacturer datasheet.
推荐
Compact Audio System
The TAS5710PHP can amplify both channels of a compact digital audio system using a single stereo package. Its documented 20 W rating, closed-loop architecture, and integrated signal processing reduce the need for separate output-stage and tone-control circuitry. The 10 V to 26 V operating range is useful when the product uses a higher-voltage bus, while the 48-pin HTQFP format supports dense board layouts. Designers must compare the amplifier's specified output power with the actual speaker impedance and channel balance, then verify thermal performance at maximum continuous output. Digital routing, clock configuration, and the manufacturer's output-filter recommendations should be implemented exactly to avoid distortion or EMI problems.

设计说明
Treat the 20 W rating as an output capability, not a design target that can be applied without checking its specified load, voltage, and test conditions. Provide continuous copper beneath the 48-pin HTQFP exposed thermal pad and multiple thermal vias into the ground plane. Confirm junction-temperature and thermal resistance limits from the complete manufacturer datasheet. For a compact enclosure, reduce allowable continuous output if copper area, ambient temperature, or neighboring heat sources prevent adequate temperature rise control.
Place input, output, and digital-interface bypass components directly beside their associated pins and use the shortest possible return paths. Keep the Class-D switching nodes compact, preserve the feedback and clock traces specified by the reference layout, and avoid routing sensitive digital nets beneath or alongside high-current output paths. The exact exposed-pad connection and output-filter geometry must follow the official recommended PCB layout rather than a generic Class-D layout.
Class-D output edges can radiate high-frequency energy even when the audio output is filtered. Use the manufacturer's recommended LC filter when EMI testing requires it, connect the filter return to a quiet analog or power ground according to the reference design, and keep the filter physically close to the amplifier outputs. Validate radiated and conducted emissions with the speaker cable and enclosure installed because cable routing can materially change high-frequency behavior.
Do not assume that two 48-pin stereo Class-D amplifiers are interchangeable solely because their packages match. Compare pin names, supply pins, digital-audio interface, clock requirements, control-register implementation, feedback connections, output-filter values, and configuration data. A replacement should also be checked for absolute maximum ratings, output power under the intended load, thermal resistance, lifecycle status, and production availability before it is approved as a drop-in device.
