1 Overview
The TAS5630PHD2EVM PurePath™ Premier Pro customer evaluation module demonstrates the
integrated circuit TAS5630PHD from Texas Instruments (TI).
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 requires only 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.
