TDA7375A中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The TDA7375A 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 guarantee the highest power performances with extremely reduced component count. The on board clip detector simplifies gain compression operation. The fault diagnostic makes it possible to detect mistakes during car radio set assembly and wiring in the car.
