TAS5815PWPR

Overview

The TAS5815PWPR is a digital-input, high-efficiency Class-D audio amplifier with integrated Class-H control and DSP. It supports stereo or mono configurations with up to 30W per channel in stereo mode at 21V into 6 ohms, or 58W in mono mode. The device features THD+N of ≤0.03% and SNR ≥110dB. Operating voltages include PVDD from 4.5V to 26.4V, and DVDD/I/O at 1.8V or 3.3V. It accepts I2S, TDM, and SPDIF inputs.

Feature Summary

• Integrates an advanced audio processor supporting sample rate conversion, parametric EQ, and dynamic range compression for signal enhancement.
• Implements proprietary Class-H envelope tracking algorithm that adjusts supply voltage dynamically to maximize system efficiency.
• Features low electromagnetic interference design requiring minimal passive components and small inductors for compact layouts.
• Includes comprehensive protection mechanisms such as over-current, thermal warning/error, and open/short load detection.

Applications

• Soundbars and home theater systems
• Smart speakers and wireless Bluetooth audio devices
• PC audio and desktop computer motherboards
• Professional conference systems and enterprise projectors

Procurement Notes

Verify the specific suffix 'PWPR' indicates tape-and-reel packaging distinct from tube variants like 'PWP'. Confirm RoHS compliance status through official documentation. Ensure compatibility with required input interfaces such as I2S or TDM for your specific application design.

Selection Notes

Select this component when digital audio input is preferred over analog to reduce noise susceptibility. The integrated DSP reduces external microcontroller dependency. Consider the wide PVDD range for flexible power supply designs in portable or fixed installations requiring high output power.

Part Context

This part belongs to Texas Instruments' TAS5815 family of high-performance digital amplifiers. It shares core architecture with evaluation modules like the TAS5815EVM. The PWPR designation specifically denotes the reel-packaged version suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Review the TAS5805M series for similar functionality if different power requirements exist. Verify software configuration compatibility if migrating between TI amplifier families with varying DSP capabilities.
