Description

The TDA7385 is an AB class audio power

amplifier, packaged in Flexiwatt 25 and designed

for high end car radio applications.

Based on a fully complementary PNP/NPN

configuration, the TDA7385 allows a rail to rail

output voltage swing with no need of bootstrap

capacitors. The extremely reduced boundary

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.
