Thanks to the DMOS output stage the TDA7561

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 behaviour of the

device by means of the I2C bus makes TDA7561

a very flexible machine.
