Overview
The TAS5630BDKDR from Texas Instruments is a high-performance, integrated Stereo Feedback Analog-Input Digital Amplifier Power Stage. This device is part of the PurePath™ HD family, designed to deliver high-quality, high-efficiency audio amplification. It can drive 4Ω speakers at up to 300W per channel in stereo Bridge-Tied Load (BTL) configuration and up to 600W in mono Parallel Bridge-Tied Load (PBTL) configuration. The amplifier features a simple passive demodulation filter for analog input signals and supports both single-ended and differential input configurations.
