DESCRIPTIONThe TDA7370 is a new technology class AB quad
channels Audio Power Amplifier in Multiwatt pack-
age designed for car radio applications.
Thanks to the fully complementary PNP/NPN out-
put configuration the high power performances of
the TDA7370 are obtained without bootstrap ca-
pacitors.
