Overview

The MAX13325/MAX13326 dual audio line drivers provide a reliable differential interface between automotive audio components. The devices feature differential inputs and outputs, integrated output diagnostics, and are controlled using an I2C interface or operate in stand-alone mode. The outputs can deliver up to 4VRMS into 100Ω loads. The MAX13325GUI/V+ buffers analog audio signals for transmission over long cable distances with a fixed gain of 12dB, whereas the MAX13326 provides a 0dB fixed gain. The diagnostics on the outputs 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 to ground and 3nF differentially. The outputs are protected according to IEC 61000-4-2 ±8kV Contact Discharge, and ±15kV Air Gap. The MAX13325/MAX13326 are specified from -40°C to +105°C and are available in a 28-pin TSSOP package with an exposed pad.
