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 100I loads. The MAX13325 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 chann...
