UNISONIC TECHNOLOGIES CO., LTD TDA7377 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 8 Copyright ? 2011 Unisonic Technologies Co., Ltd QW-R107-064.A 2 x 30W DUAL/QUAD POWER AMPLIFIER FOR CAR RADIO ? DESCRIPTION The UTC TDA7377 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. ?
