package specially intended for car radio applica-

tions. Thanks to the DMOS output stage the

TDA7562 has a very low distortion allowing a

clear powerful sound.

This device is equipped with a full diagnostics array

that communicates the status of each speaker

through the I2C bus.

The possibility to control the configuration and the

behaviour of the device by means of the I2C bus

makes TDA7562 a very flexible machine.
