Maxim Integrated MAX13325
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 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.
