Typical Operating Circuit
General Description
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 trans-
mission 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
Q
8kV Contact Discharge, and Q15kV Air Gap. The
MAX13325/MAX13326 are specified from -40NC to
+105NC and are available in a 28-pin TSSOP package
with an exposed pad.
