Description
The TDA7566 is a new BCD technology quad
bridge type of car radio amplifier in Flexiwatt25
package specially intended for car radio
applications.
Flexiwatt25
Thanks to the DMOS output stage the TDA7566
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 TDA7566 a very flexible product.
