TAS5704PAP

Overview

The TAS5704PAP is a 20-W stereo, 10- to 26-V, digital input, Class-D audio amplifier with speaker EQ, DRC & H/W control. It features two serial audio inputs supporting four audio channels. The device operates within a supply voltage range of 3V to 3.6V and 10V to 26V. Maximum output power is 20.6W into an 8-Ohm load or 18.1W into a 4-Ohm load per channel. It utilizes an HTQFP-64 package.

Feature Summary

• Integrates digital signal processing for speaker equalization and dynamic range compression
• Supports hardware control interfaces for system management
• Accepts dual serial audio inputs for multi-channel configuration

Applications

• Portable multimedia devices requiring high-efficiency stereo amplification
• Smart home audio systems with digital input capabilities
• Automotive infotainment speakers driven by digital sources

Procurement Notes

Verify the specific suffix (e.g., PAP) against the manufacturer's official ordering guide to confirm pinout and packaging details. Ensure compatibility with the target PCB footprint for the HTQFP-64 package. Confirm that the design supports the required 10V to 26V supply rails for optimal performance. Check for moisture sensitivity level requirements during assembly.

Selection Notes

Select this component when a stereo Class-D amplifier with integrated DSP functions is required. It is suitable for applications needing digital audio inputs and hardware control. Consider the thermal performance in the HTQFP-64 package relative to the enclosure constraints. Verify that the system architecture can support the necessary serial audio protocols.

Part Context

This part belongs to Texas Instruments' TAS570x series of digital audio power amplifiers. It is designed for efficient audio reproduction in portable and fixed installations. The series emphasizes integration of digital processing features to reduce external component count. It serves as a solution for modern digital audio systems requiring high fidelity and efficiency.

Replacement Considerations

Check for TAS5704 variants with different suffixes for packaging changes. Verify if TAS5705 or TAS5706 offer compatible pinouts or enhanced features. Ensure substitute parts maintain the same voltage range and digital interface requirements.
