TDA7370B is a new technology class AB quad channels Audio Power Amplifier in Multiwatt package designed for car radio applications. It has minimum external component count, high current capability, no bootstrap capacitors, no Boucherot cells, clip detector output, high output power, high application flexibility, fixed gain, very low stand-by current, no switch on/off noise protections, output AC/DC short circuit to GND and to VS, very inductive loads overrating chip temperature, load dump voltage, fortuitous open GND, reverse battery ESD.
The TDA7370B is a new technology class AB quad channels Audio Power Amplifier in Multiwatt package designed for car radio applications. It features a fully complementary PNP/NPN output configuration to achieve high power performance without bootstrap capacitors. The device includes protections against short circuits, overrating chip temperature, and reverse battery, with a very low stand-by current of 1A typical.
