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 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 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.
