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

    ... V/ms. 3.4 DC offset detector The TDA7560 integrates a DC offset detector to avoid that an anomalous DC offset on the inputs of the amplifier may be multiplied by the gain and result in a dangerous large offset on the outputs which may lead to speakers damage for overheating. The feature is enabled by the MUTE pin (according to signal on the inputs ...
