TDA7374B - DUAL BRIDGE AUDIO AMPLIFIER

General 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 output configuration the high power performances of the TDA7374B are obtained without bootstrap capacitors.

Key Features

  • is added to avoid destruction, if during fitting to the car, a mistake on the connection of the supply is made. Open Ground When the radio is in the ON condition and the ground is accidentally opened, a standard audio amplifier will be damaged. On the TDA7374B protection diodes are included to avoid any damage. Inductive Load A protection diode is provided to allow use of the TDA7374B with inductive loads. TDA7374B DC Voltage The maximum operating DC voltage for the TDA7374B is 18V. However the.
