Overview
The TDA7560H, produced by STMicroelectronics, is a high-performance quad bridge car radio amplifier designed using advanced BCD (Bipolar/CMOS/DMOS) technology. This amplifier is packaged in the Flexiwatt 25 format, available in both horizontal and vertical configurations. It is engineered to deliver superior output power and exceptional audio quality, making it an ideal choice for high-power car radio systems.
The device features a fully complementary P-Channel/N-Channel output structure, enabling a rail-to-rail output voltage swing. This design, combined with high output current and minimized saturation losses, sets new standards in the car-radio field with unparalleled distortion performance.
