Texas Instruments' TAS5630DKD 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. 

The TAS5630DKD2EVM PurePath™ HD customer evaluation module demonstrates the integrated circuit TAS5630DKD. This EVM is configured with 2 BTL channels and the possibility to apply either a single ended or a differential analog input signal. 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.
