ORDERING NUMBERS:
TDA7360 TDA7360HS
Thanks to the fully complementaryPNP/NPN output configuration the high power performance of
the TDA7360 is obtained without bootstrap capacitors.
A delayed turn-on mute circuit eliminates audible
on/off noise, and a novel short circuit protection
system prevents spurious intervention with highly
inductiveloads.
The device provides a circuit for the detection of
clipping in the output stages. The output, an open
collector, is able to drive systems with automatic
volumecontrol.
