Product overview
概要
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.
