DESCRIPTION

The TDA7296A is a monolithic integrated circuit

in Multiwatt15 package, intended for use as audio

class AB amplifier in Hi-Fi field applications

(Home Stereo, self powered loudspeakers, Top-

class TV). Thanks to the wide voltage range and

to the high out current capability it is able to sup-

ply the highest power into both 4

even in presence of poor supply regulation, with

high Supply Voltage Rejection.

The built in muting function with turn on delay

simplifies the remote operation avoiding switching

on-off noises.

The device provides a circuit for the detection of

clipping in the output stages. The output, on open

collector, is able to drive system with automatic

level control.
