TABLE 2. 81840 ABSOLUTE MAXIMUM RATINGS1,2,3,4
1. The LMUX MCM is designed to operate with power supply voltages ranging
from ±5.2V to ±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. T
A = 25° C unless otherwise specified.
