3 Description

The

TAS5352A

device

is

a

high-performance,

integrated

stereo

digital

amplifier

power

stage

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.

The TAS5352A 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,

overcurrent

protection,

undervoltage

protection, overtemperature 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.
