Overview
The TDA7560, produced by STMicroelectronics, is a groundbreaking BCD (Bipolar / CMOS / DMOS) technology class AB audio power amplifier. It is designed for high-power car radio applications and comes in the Flexiwatt 25 package. The amplifier features a fully complementary P-Channel/N-Channel output structure, allowing for a rail-to-rail output voltage swing. This design, combined with high output current and minimized saturation losses, sets new power standards in the car-radio market with unparalleled distortion performance.
