Overview
The TDA7560 is a class AB audio power amplifier developed by STMicroelectronics, utilizing breakthrough BCD (Bipolar / CMOS / DMOS) technology. It is designed for high-power car radio applications and is packaged in the Flexiwatt 25 format. This amplifier is notable for its fully complementary P-Channel/N-Channel output structure, which allows for a rail-to-rail output voltage swing, high output current, and minimized saturation losses. This results in unparalleled distortion performances in the car-radio field.
