The TDA7569BLV is the most advanced BCD technology quad bridge car radio amplifier of his family, including a wide range of innovative features.

The TDA7569BLV is equipped with the most complete diagnostics array that communicates the status of each speaker through the I2C bus.

The dissipated output power under average listening condition is significantly reduced when compared to the conventional class AB solutions, thanks to the patented solution. Moreover it has been designed to be very robust against several kinds of misconnections.

It is moreover compliant to the most recent OEM specifications for low voltage operation (so called 'start-stop' battery profile during engine stop and re-start), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection.
