TDA7375 Car Audio Amplifier Circuit

 

The following circuit shows about 35W quadruple amplifier and 2 x 25W bridge amplifier based on the TDA7375 IC, this circuit requests the minimum of external components. Although the first conception went to car applications , to give him/it in a great variety of applications of low potency. That integrated circuit is ideal in the situation in that is wanted a reasonable potency and with a Power tension relatively low for your operation. That circuit drawn below it uses the basic configuration of quadruple amplifier, but using a configuration in bridge, it can be obtained about 4 times the maximum potency. In that configuration of quadruple amplifier it can be used as amplifier end of systems surround

IC TDA7375 is a new technology class AB car 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 guaranteesthe 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.
