Overview
The TAS5706PAPR is a digital-input, 20-W stereo Class D speaker amplifier manufactured by Texas Instruments. It utilizes a closed-loop feedback architecture to enhance sound quality and provide greater speaker control. The device features an I2S interface and includes integrated Speaker EQ and Dynamic Range Control (DRC). It operates within a temperature range of 0°C to +85°C and is housed in a 64-pin HTQFP package.
Feature Summary
- Closed-loop feedback architecture for improved audio fidelity
- Integrated Speaker EQ and Dynamic Range Control
- Digital I2S input interface
Applications
- LCD TV backlight supply operation
- High-fidelity audio systems requiring EMC compliance
- Consumer electronics with limited power supply headroom
Procurement Notes
Verify the specific suffix 'PAPR' against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure compatibility with the system's thermal management requirements for the HTQFP-64 package. Confirm that the closed-loop design aligns with the target application's noise sensitivity standards before finalizing procurement.
Selection Notes
Select this component when high efficiency and low distortion are required without analog input stages. The closed-loop feature distinguishes it from open-loop alternatives, offering better performance under varying load conditions. Consider the 64-pin package size relative to available PCB space and the need for integrated DSP-like functions such as DRC.
Part Context
This part belongs to the TAS5706A series of digital audio amplifiers. It represents Texas Instruments' approach to integrating advanced audio processing directly into the power stage. The series targets applications where board space is limited but audio quality must remain high, leveraging digital inputs to simplify system design.
Replacement Considerations
Check for TAS5706APAPR or TAS5706BPAPR variants for potential pin-compatible upgrades or revisions. Verify if newer generations like the TAS5760 series offer enhanced power output or different packaging options suitable for the same footprint.
