Overview
The TAS5710PHPR is a 20-W stereo digital audio power amplifier manufactured by Texas Instruments. It features a closed-loop I2S architecture with integrated equalization (EQ), dynamic range compression (DRC), and feedback capabilities. The device operates on an 8V to 26V supply voltage and utilizes a 48-pin HTQFP package. It supports sampling rates from 8kHz to 48kHz, delivering high-fidelity audio with low total harmonic distortion plus noise.
Feature Summary
- Integrates closed-loop I2S digital audio processing with built-in EQ and DRC for signal optimization
- Supports direct connection to digital audio sources without external DAC requirements
- Includes comprehensive protection mechanisms against thermal, short-circuit, and DC offset faults
Applications
- High-fidelity home audio systems
- Commercial sound reinforcement equipment
- Multimedia speaker arrays
- Digital audio receivers
Procurement Notes
Verify the specific suffix 'PHPR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component status remains active for new designs, as previous iterations in this family may have transitioned to non-recommended-new-design status. Ensure compatibility with the target PCB footprint for the 48-pin HTQFP package during procurement planning.
Selection Notes
Select this component when a stereo Class-D amplifier requires integrated digital signal processing features such as equalization and dynamic range compression. It is suitable for applications demanding high efficiency and minimal external component count. Consider the 8V-26V operating range to ensure alignment with the system's power supply rails and thermal management capabilities.
Part Context
This part belongs to the Texas Instruments TAS57xx series of digital audio power amplifiers. It is designed to replace older analog or less integrated digital solutions by combining power output with DSP functions. The device is distinct from the TAS5711 and TAS5719 due to its specific closed-loop feedback and DRC integration profile within the same package family.
Replacement Considerations
The TAS5711PHPR and TAS5719PHPR are documented substitutes within the same product family. Verify pin-to-pin compatibility and software configuration differences regarding the specific DSP algorithms before swapping.
