DESCRIPTION

The TDA7575 is a new BCD technology DUAL

BRIDGE type of car radio amplifier in PowerSO36

package specially intended for car radio applications.

Thanks to the DMOS output stage the TDA7575 has

a very low distortion allowing a clear powerful sound.

Among the features, its superior efficiency perfor-

mance coming from the internal exclusive structure,

makes it the most suitable device to simplify the ther-

mal 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

bility of driving loads down to 1

Ω paralleling the outputs

into a single channel. It is also possible to disable the

I2C and control the TDA7575 by means of the usual ST-

BY and MUTE pins.
