Description

The TDA7575B is a new MOSFET dual bridge

amplifier specially intended for car radio

applications. Thanks to the DMOS output stage

the TDA7575B has a very low distortion allowing

a clear powerful sound.

Among the features, its superior efficiency

performance coming from the internal exclusive

structure, makes it the most suitable device to

simplify the thermal management in high power

sets.The dissipated output power under average

listening condition is in fact reduced up to 50%

when compared to the level provided by

conventional class AB solutions.

This device is equipped with a full diagnostic array

that communicates the status of each speaker

through the I2C bus. The TDA7575B has also the

possibility of driving loads down to 1Ω paralleling

the outputs into a single channel. It is also

possible to disable the I2C and control the

TDA7575B by means of the usual ST-BY and

MUTE pins.
