TDA7375AV 2 x 37 W dual/quad power amplifier for car radio Features High output power capability 2 x 43 W max./4 2 x 37 W/4 EIAJ 2 x 26 W/4 14.4 V, 1 kHz, 10 % 0 03 4 x 7 W/4 14.4 V, 1 kHz, 10 % Multiwatt15 4 x 12 W/2 14.4 V, 1 kHz, 10 % Minimum external components count: Very inductive loads No bootstrap capacitors Fortuitous open GND No Boucherot cells Reversed battery Internally fixed gain (26 dB BTL) ESD Standby function (CMOS compatible) No audible pop during standby operations Description Diagnostics facility for: The TDA7375AV is a technology class AB car Clipping radio amplifier able to work either in dual bridge or Out to GND short quad single ended configuration. Out to V short S The exclusive fully complementary structure of Soft short at turn-on the output stage and the internally fixed gain Thermal shutdown proximity guarantee the highest possible power Protections: performances with extremely reduced component Output AC/DC short circuit: to GND, to V count. S and across the load The on-board clip detector simplifies gain Soft short at turn-on compression operation. The fault diagnostics Overrating chip temperature with soft makes it possible to detect mistakes during car thermal limiter radio set assembly and wiring in the car. Load dump voltage surge Table 1.
