  • The TDA7569BDLVPD is the most advanced BCD technology quad bridge car radio amplifier, including a wide range of innovative features.

    The TDA7569BDLVPD is equipped with the most complete diagnostics array that communicates the status of each speaker through the I2C bus. The differential input stage improves the disturbance rejection.
    The dissipated output power under average listening condition is significantly reduced when compared to the conventional class AB solutions, thanks to the innovative internal design. 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), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection.

    Key Features
