6.4.1.1 Input Common-Mode Voltage Range

The LMC7101 does not exhibit phase inversion when an input voltage exceeds the negative supply voltage. Figure 6-1 shows an input voltage exceeding both supplies with no resulting phase inversion of the output.

The absolute maximum input voltage is 300mV beyond either rail at room temperature. Voltages greatly exceeding this maximum rating, as in Figure 6-2, can cause excessive current to flow in or out of the input pins, thus adversely affecting reliability.

LMC7101 Input Voltage
The input voltage signal exceeds the amplifier power supply voltage with no output phase inversion.
Figure 6-1 Input Voltage
LMC7101 Input Signal
The ±7.5V input signal greatly exceeds the 3V supply in Figure 6-3 causing no phase inversion due to RI.
Figure 6-2 Input Signal

Applications that exceed this rating must externally limit the maximum input current to ±5mA with an input resistor as shown in Figure 6-3.
