Overview
The TAS5705PAPR is a Class-D audio amplifier manufactured by Texas Instruments, housed in a 64-HTQFP (10x10) surface-mount package. It delivers 20W per channel into an 8-ohm load with dual power supplies ranging from 8V to 23V. The device supports stereo output configurations including dedicated channels for stereo headphones and subwoofers. Key electrical specifications include a maximum operating temperature of +85°C and a quiescent current typical of low-power operation.
Feature Summary
- Integrates digital input interfaces including I2S and control protocols such as I2C for system configuration.
- Includes built-in protection mechanisms against short circuits and thermal overload to ensure operational reliability.
- Features hardware-controlled volume adjustment and mute functions for simplified system integration.
Applications
- Stereo audio amplification for consumer electronics
- Headphone driver circuits requiring integrated power management
- Subwoofer channel amplification in multi-channel audio systems
Procurement Notes
Verify the specific suffix 'PAPR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 64-pin HTQFP footprint matches the target PCB layout dimensions. Ensure compatibility with the intended supply voltage range of 8V to 23V before finalizing component selection.
Selection Notes
Select this component when a high-efficiency Class-D solution is needed for stereo applications with separate headphone and subwoofer outputs. Consider the 64-pin package size constraints and the requirement for external passive components. Verify that the digital interface requirements align with the host processor's I2S and I2C capabilities.
Part Context
This part belongs to the TAS5705 series of audio power amplifiers designed for high-fidelity sound reproduction. It represents a specialized variant within Texas Instruments' portfolio focused on integrating multiple audio output channels into a single compact IC, reducing board space compared to discrete solutions.
Replacement Considerations
Check for TAS5705PAPRG4 as a potential lead-free or environmental compliance variant within the same functional family. Verify pinout compatibility if substituting with other members of the TAS57xx series.
