TAS5731PHP

Overview

The TAS5731PHP is a stereo digital audio power amplifier manufactured by Texas Instruments, housed in an HTQFP-48 package. It delivers up to 60 W of output power and operates within a supply voltage range of 8 V to 24 V. The device supports two-channel I2S input with sampling rates from 8 kHz to 48 kHz. It features integrated DSP capabilities including speaker equalization and dynamic range compression. The amplifier achieves high efficiency up to 90% and includes built-in protections against thermal overload and short circuits.

Feature Summary

• Integrates a digital signal processor for advanced audio management functions such as speaker equalization and dynamic range compression.
• Supports flexible multi-mode operation, allowing configuration for standard stereo or 2.1 channel setups using a single device.
• Features a fully programmable data path that routes discrete audio channels directly to internal bridge-tied load drivers.

Applications

• Liquid crystal display televisions
• Light emitting diode televisions
• Sound bars

Procurement Notes

Verify the specific suffix 'PHP' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the required pin-compatible variant, as suffixes may indicate differences in reel specifications rather than functional changes. Cross-reference the datasheet revision to confirm current production status and recommended operating conditions.

Selection Notes

Select this component when designing systems requiring high-efficiency digital amplification with integrated signal processing. It is suitable for applications needing direct connection to digital processors without external analog conversion. Consider its wide supply voltage range and low quiescent current for battery-powered or standard DC-supplied consumer electronics. Verify compatibility with the target speaker impedance and required output power levels.

Part Context

This device belongs to the TAS5731M series of digital audio power amplifiers. It is designed to replace legacy analog solutions by integrating DSP functions directly into the power stage. The component is pin-to-pin compatible with other devices in the family, facilitating design upgrades. It targets the consumer audio market where space constraints and audio fidelity are critical design parameters.

Replacement Considerations

The TAS5727 is documented as a pin-to-pin compatible alternative within the same product family. Verify electrical parameter alignment and software configuration requirements before substitution. No other specific substitute part numbers are confirmed in the provided public documentation.
