2 Description

The TDA7560 is a breakthrough BCD (Bipolar /

CMOS / DMOS) technology class AB Audio Power

Amplifier in Flexiwatt 25 package designed for

high power car radio. The fully complementary P-

Channel/N-Channel output structure allows a rail

to rail output voltage swing which, combined with

high output current and minimised saturation loss-

es sets new power references in the car-radio

field, with unparalleled distortion performances.
