Description

The TDA7375 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 guarantees the 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.

Absolute Maximum Ratings (Ta = 25°C)

1. Vop : Operating Supply Voltage = 18 V
2. VS : DC Supply Voltage = 28 V
3. Vpeak : Peak Supply Voltage (for t = 50ms) = 50 V
4. IO : Output Peak Current (not repetitive t = 100µs) = 4.5 A
5. IO : Output Peak Current (repetitive f > 10Hz) = 3.5 A
6. Ptot : Power Dissipation (Tcase = 85°C) = 36 W
7. Tstg, Tj : Storage and Junction Temperature = -40 to 150 °C
