MAX13325/MAX13326 are dual automotive audio line drivers with I2C control and diagnostic capabilities, providing a reliable differential interface between automotive audio components. They feature differential inputs and outputs, integrated output diagnostics, and can be controlled using an I2C interface or operate in standalone mode. The outputs can deliver up to 4VRMS signals with a fixed gain of 12dB or 0dB. The output diagnostics report conditions on a per channel basis, including short to GND, short to battery, overcurrent, overtemperature, and excessive offset. The output amplifiers can drive capacitive loads up to 4nF. MAX13325/MAX13326 are designed for automotive applications and can operate in a temperature range of -40°C to +105°C.
