TDA7375 Datasheet, PDF (2/15 Pages) STMicroelectronics – 2 x 35W DUAL/QUAD POWER AMPLIFIER FOR CAR RADIO

TDA7375
DESCRIPTION
The TDA7375 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-
ABSOLUTE MAXIMUM RATINGS
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.
