Overview
The TDA7560L, produced by STMicroelectronics, is a high-performance class AB audio power amplifier designed specifically for high-power car radio applications. Utilizing advanced BCD (Bipolar / CMOS / DMOS) technology, this amplifier is packaged in the Flexiwatt 25 format. It features a fully complementary P-Channel/N-Channel output structure, enabling a rail-to-rail output voltage swing, high output current, and minimized saturation losses. This results in unparalleled distortion performance and sets new power standards in the car-radio field.
