TDA7374 is a class AB audio dual bridge power amplifier from STMicroelectronics. It features fully complementary PNP/NPN output configuration and no bootstrap capacitors.
The TDA7374 is a class AB audio dual bridge power amplifier designed specifically for car radio applications. It operates in a Multiwatt 15 package and is characterized by a minimum external component count, requiring no bootstrap capacitors or Boucherot cells. The device offers high output power with a fixed gain of 26 dB and very low stand-by current (1 µA typical).
