TAS5630PHD2EVM: 318W x2 @ 4Ω, 25 ~ 50V in, Class D

Summary

This user’s guide describes the operation of the evaluation module for the TAS5630 300W Stereo Feedback Analog-Input Digital Amplifier from Texas Instruments. The user’s guide also provides measurement data and design information including the schematic, BOM, and PCB layout.

The TAS5630PHD2EVM PurePath™ Premier Pro customer evaluation module demonstrates the integrated circuit TAS5630PHD from Texas Instruments.

The TAS5630PHD is a high-performance, integrated Stereo Feedback Analog-Input Digital Amplifier

Power Stage designed to drive 4Ω speakers at up to 300W per channel. This amplifier requiresonly a simple passive demodulation filter to deliver high-quality, high-efficiency audio amplification.

This EVM is configured with 2 BTL channels and the possibility to apply either a single ended or a differential analog input signal. It is also possible to configure the two BTL channels into one parallel BTL (PBTL) channel.

The OPA1632 is a High Performance Fully Differential Audio Op Amp designed to allow operation with single ended or differential input signals to the EVM.

This EVM is a complete stereo analog input 2 × 300 W power amplifier ready for evaluation and great music.
