Datasheet

- production data

Features

 High output power capability:

– 4 x 45 W / 4

 max.

– 4 x 26 W / 4

 @ 14.4 V, 1 kHz, 10 %

 Low distortion

 Low output noise

 Standby function

 Mute function

 Automute at min. supply voltage detection

 Low external component count:

– Internally fixed gain (26 dB)

– No external compensation

– No bootstrap capacitors

Protections:

 Output short circuit to gnd, to VS, across the

load

 Very inductive loads

 Overrating chip temperature with soft thermal

limiter

 Load dump voltage

 Fortuitous open GND

 Reversed battery

 ESD

Description

The TDA7388 is an AB class audio power

amplifier, packaged in Flexiwatt 25 and designed

for high end car radio applications.

Based on a fully complementary PNP/NPN

configuration, the TDA7388 allows a rail to rail

output voltage swing with no need of bootstrap

capacitors. The extremely reduced boundary

components count allows very compact sets.
