Product Introduction

Overview

The TAS5352A, produced by Texas Instruments, is a high-performance, integrated stereo digital amplifier power stage. This device is designed to drive a 4-Ω bridge-tied load (BTL) at up to 125 W per channel with low harmonic distortion, low integrated noise, and low idle current. It features a comprehensive protection system, including undervoltage protection, overtemperature protection, overload protection, short-circuit protection, and a PWM activity detector. The TAS5352A also includes a power-on-reset (POR) circuit to eliminate the need for power-supply sequencing, enhancing system reliability and performance.
