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.

This is preliminary information on a new product now in development. Details are subject to change without notice.
