LINEAR INTEGRATED CIRCUIT
2 x 35W DUAL/QUAD POWER
AMPLIFIER FOR CAR RADIO
„ DESCRIPTION
The UTC PA7375 is a class AB car radio amplifier for car
radio, it can work either in dual bridge or quad single ended
configuration. The exclusive fully complementary structure of the
output stage and the internally fixed gain guarantees the highest
possible power performances with few external components.
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.
