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 performance and affect reliability. 4. T A = 25 C unless otherwise specified.
