6.1.2 Input Common-Mode Voltage Range

The LMC7111 does not exhibit phase inversion when an input voltage exceeds the negative supply voltage.

The absolute maximum input voltage is 300mV beyond either rail at room temperature. Voltages greatly exceeding this maximum rating can cause excessive current to flow in or out of the input pins, adversely affecting reliability.

Applications that exceed this rating must externally limit the maximum input current to ±5mA with an input resistor as shown in Figure 6-1.
