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.
