Thanks to the DMOS output stage the TDA7562B
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
behavior of the device by means of the I²C bus
makes TDA7562B a very flexible machine.
