TDA7566 - 4 x 40 W multifunction quad power amplifier

Features
DMOS power outputHigh output power capability 4 x 25 W/4  @ 14.4 V, 1 kHz, 10 % THD, 4 x 40 W max. powerMax. output power 4 x 60 W/2 Full I2C bus driving:StandbyIndependent front/rear soft play/muteSelectable gain 26 dB - 12 dBI2C bus digital diagnosticsFull fault protectionDC offset detectionFour independent short circuit protectionClipping detector pin with selectable threshold (1%, 10%)ESD protection
Description
The TDA7566 is a new 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 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.
