DESCRIPTION
The TDA7562 is a new BCD technology Quad
Bridge type of car radio amplifier in Flexiwatt27V
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 I
2
C bus.The possibility
to control the configuration and the behaviour of
the device by means of the I
2
C bus makes
TDA7562 a very flexible machine.
