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
losses sets new power references in the car-radio
field, with unparalleled distortion performances.
