1. The LMUX MCM is designed to operate with power supply voltages ranging

from Â±5.2V to Â±20VDC.

2. The maximum voltage each input AIN(128:1) may see without damage is

+35V to -35V with respect to ground.

3. Stresses above the absolute maximum rating may cause permanent damage

to the device. Extended operation at the maximum levels may degrade per-

formance and affect reliability.

4. TA = 25Â°C unless otherwise specified.
