Description:

The TDA7561 is a BCD technology quad bridge type of car radio amplifier in Flexiwatt25 package specially intended for car radio applications. 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.
