DESCRIPTION

The TDA737

7 is a new technology class AB car

radio amplifier able to work either in DUAL

BRIDGE or QUAD SINGLE ENDED configuration.

The exclusive fully complementary structure of the

output stage and the internally fixed gain guaran-

tees the highest possible power performances

with extremely reduced component count. The

on-board clip detector simplifies gain compression

operation. The fault diagnostics makes it possible

to detect mistakes during car radio set assembly

and wiring in the car.
