TAS5731MPHP

Overview

The TAS5731MPHP is a Class-D digital audio power amplifier manufactured by Texas Instruments, housed in a 48-pin HTQFP package. It delivers up to 60 W of stereo output power with an efficiency reaching 90%. The device operates on a wide power supply range from 8 V to 24 V and accepts I2S digital inputs at sampling rates between 8 kHz and 48 kHz. It features integrated DSP capabilities, including speaker EQ and dynamic range compression, supporting 2.1 mode configurations.

Feature Summary

• Integrates digital signal processing for speaker equalization and dynamic range compression
• Supports 2.1 channel configuration within a single device architecture
• Accepts direct I2S digital audio inputs without requiring external DACs
• Provides high operational efficiency to minimize thermal management requirements

Applications

• LCD television systems
• LED television displays
• Sound bar audio modules

Procurement Notes

Verify the specific suffix 'MPHP' against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure the design supports the required 8V to 24V power stage supply and 3.3V digital logic levels. Confirm that the application environment accommodates the specified operating temperature range and humidity sensitivity classifications before finalizing procurement.

Selection Notes

Select this component when a digital input interface is preferred over analog signals to reduce noise susceptibility. It is suitable for designs requiring integrated audio processing features such as parametric equalization. Consider its compatibility with standard I2S sources and the need for a wide voltage input range to accommodate various power supply architectures in consumer electronics.

Part Context

This part belongs to the TAS5731M series of digital audio amplifiers. It is designed to replace or complement previous generations like the TAS5727, offering enhanced processing capabilities. The device integrates the power stage and control logic into a single solution, simplifying the bill of materials for high-fidelity audio applications in compact form factors.

Replacement Considerations

The TAS5727 is documented as a pin-to-pin compatible alternative within the same family. Verify electrical specifications and feature sets match the original design requirements before substituting.
