1. The LMUX MCMis designed to operate with power supply voltages ranging
from±5.2V to ±20VDC.
2. The maximumvoltage each input AIN(128:1) may see without damage is
+35V to -35V with respect to ground.
3. Stresses above the absolute maximumrating may cause permanent damage
to the device. Extended operation at the maximumlevels may degrade per-
formance and affect reliability.
