3 Description

The TAS5342LA is a high-performance, integrated

stereo digital amplifier power stage designed to drive

a 4-Ω bridge-tied load (BTL) at up to 100 W per

channel with low-harmonic distortion, low-integrated

noise, and low-idle current.

The TAS5342LA has a complete protection system

integrated on-chip, safeguarding the device against a

wide range of fault conditions that could damage the

system. These protection features are short-circuit

protection, over-current protection, under voltage

protection, over temperature protection, and a loss of

PWM signal (PWM activity detector).

A power-on-reset (POR) circuit is used to eliminate

power-supply sequencing that is required for most

power-stage designs.
