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 unparal-
leled distortion performances.
PROTECTIONS:
OUTPUT SHORT CIRCUIT TO GND, TO V S ,
ACROSS THE LOAD
VERY INDUCTIVE LOADS

SOFT THERMAL LIMITER
