TAS5704PAPR

Overview

The TAS5704PAPR is a 20-W stereo, Class-D digital audio power amplifier from Texas Instruments. It operates on a 10-V to 26-V supply and features two serial audio inputs supporting four audio channels. The device integrates speaker equalization (EQ) and dynamic range compression (DRC) with hardware control capabilities. It utilizes an HTQFP-64 package for surface-mount installation. Key electrical specifications include a maximum output power of 20.6 W into an 8-Ohm load, with a total harmonic distortion plus noise (THD+N) of 0.05%. The operational temperature range spans from 0°C to +85°C.

Feature Summary

• Integrates speaker equalization and dynamic range compression with hardware control
• Supports dual serial audio inputs for four-channel operation
• Class-D architecture for high-efficiency stereo audio amplification

Applications

• Portable multimedia devices requiring efficient stereo audio
• Digital audio systems needing integrated speaker management
• Consumer electronics utilizing I2S digital audio interfaces

Procurement Notes

Verify the specific suffix 'PAPR' against the manufacturer's current ordering guide to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the HTQFP-64 footprint matches your PCB design constraints. Check for any recent product discontinuance notifications or lifecycle status updates directly from Texas Instruments documentation before finalizing procurement plans.

Selection Notes

Select this component when a stereo Class-D amplifier with integrated digital signal processing for speaker EQ and DRC is required. Ensure the system supports the necessary 10-V to 26-V supply voltage range and I2S digital input interface. Consider the HTQFP-64 package size and thermal requirements relative to the application's enclosure and heat dissipation capabilities.

Part Context

The TAS5704 belongs to Texas Instruments' TAS570x series of digital audio power amplifiers. This family focuses on providing high-efficiency amplification combined with onboard audio processing features. The TAS5704 specifically targets stereo applications, offering a compact solution for driving speakers in portable and consumer electronic devices without external DSP components.

Replacement Considerations

Consult Texas Instruments official substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering similar models within the TAS570x family or other TI Class-D amplifiers.
