DESCRIPTION
The TDA7374B is a new technology class AB
Audio Dual Bridge Power Amplifier in Multiwatt
package designed for car radio applications.
Thanks to the fully complementary PNP/NPN out-
put configuration the high power performances of
the TDA7374B are obtained without bootstrap ca-
pacitors.
