## Description

The TAS5634DDVR from Texas Instruments is a PWM-input, Class-D amplifier power stage designed for high-fidelity audio applications. It offers flexible configurations, capable of delivering 300 W per channel in stereo mode into a 6 Ω load or 600 W in mono PBTL configuration into a 3 Ω load. The amplifier operates over a wide supply voltage range of 12 to 62 V.

Key features include integrated closed-loop feedback, which contributes to excellent audio performance with low total harmonic distortion (THD) of 0.025% at 1 W into 6 Ω, a signal-to-noise ratio (SNR) greater than 105 dB, and a power supply rejection ratio (PSRR) greater than 70 dB. The device boasts high efficiency, exceeding 91% at full output power and over 75% at 1/8 output power, which helps reduce heatsink size requirements. Integrated MOSFETs and comprehensive protection features, including undervoltage, over temperature, overcurrent, and short circuit protection, enhance reliability.

The TAS5634DDVR is housed in a 44-pin HTSSOP package with a thermal pad. It is compatible with TI's digital-input audio processors and modulators, making it suitable for home audio systems, soundbars, and other demanding audio applications.
