TDA7562 is a new BCD technology Quad Bridge type of car radio amplifier in Flexiwatt27V package specially intended for car radio applications. 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 I2C bus.The possibility to control the configuration and the behaviour of the device by means of the I2C bus makes TDA7562 a very flexible machine.
The TDA7562 is a BCD technology quad power amplifier featuring DMOS output stages designed specifically for car radio applications. It delivers high output power capability (up to 4x25W/40 or 4x35W EIAJ) and includes full I2C bus driving for independent front/rear soft play/mute control and selectable gain settings.
The device incorporates a comprehensive diagnostics array that communicates the status of each speaker through the I2C bus, allowing for full fault protection including DC offset detection and four independent short circuit protections. It also features a clipping detector pin with selectable thresholds.
