Overview
The TAS5709PHPR is a Class-D stereo audio power amplifier manufactured by Texas Instruments. It delivers 20.6 W of output power into an 8-ohm load with a total harmonic distortion plus noise (THD+N) of 0.06%. The device operates on a supply voltage range from 8 V to 24 V and supports I2S digital audio input. It is housed in a 48-pin HTQFP package with exposed pad for surface-mount installation, designed for operation within a temperature range of 0°C to +85°C.
Feature Summary
- Stereo Class-D architecture providing high-efficiency audio amplification
- Digital I2S interface for direct connection to digital audio sources
- Integrated thermal protection and short-circuit protection mechanisms
Applications
- Portable multimedia speakers
- Home theater systems
- Automotive infotainment audio modules
Procurement Notes
Verify the specific suffix PHPR indicates Reel packaging when ordering. Confirm the HTQFP-48 footprint matches the target PCB layout. Ensure the design supports the required 8V to 24V supply rails. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.
Selection Notes
Select this component for applications requiring high-power stereo output from a digital source. The 20.6W rating suits 8-ohm loads efficiently. Consider the 48-pin HTQFP package size for space constraints. Verify that the system can provide the necessary heat dissipation for the exposed pad design under maximum load conditions.
Part Context
This part belongs to the TAS5709 series of digital audio amplifiers. It shares architectural similarities with other members like the TAS5709PHP, differing primarily in packaging format. The series targets consumer electronics needing robust, high-fidelity sound reproduction with minimal external components.
Replacement Considerations
TAS5709PHP is a tray-packaged equivalent with identical electrical characteristics. TAS5709APHPR offers the same performance in reel or cut-tape formats. Verify pin compatibility and thermal requirements before substituting.
