4x25W CAR AMPLIFIER TDA7381 ELECTRONIC DIAGRAM

4x25W CAR AMPLIFIER TDA7381 ELECTRONIC DIAGRAM

The extremely reduced components count allows very compact sets. The on-board clipping detector simplifies gain compression operations. The fault diagnostics makes it possible to detect mistakes during Car- Radio assembly and wiring in the car.

Absolute maximum ratings of IC TDA7295 IC
  •     Operating supply voltage = 18 V
  •     DC supply voltage = 28 V
  •     Peak supply voltage (t = 50 ms) = 50 V
  •     Output peak current Repetitive (duty cycle 10 % at f = 10 Hz) = 3 A
  •     Output peak current Non repetitive (t = 100 µs) = 4A
  •     Power dissipation, (Tcase = 70 °C) = 80 W
  •     Junction temperature = 150 °C
  •     Storage temperature = -40 to 150 °C
