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
,
S
The fullycomplementaryP-Channel/N-Channel
output structure allowsa rail to rail outputvoltage
swingwhich, combined with high output current
and minimised saturation losses sets new power
referencesin the car-radiofield, with unparalleleddistortion performances.
