Description
The TDA7560A is a breakthrough BCD (Bipolar /
CMOS / DMOS) technology class AB audio power
amplifier in Flexiwatt 27 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 minimized saturation losses sets new power
references in the car-radio field, with unparalleled
distortion performances.
