Application Information

1.0 Input Common-Mode Voltage Range

The LMC6462/4 has a rail-to-rail input common-mode volt-

age range.

Figure 1 shows an input voltage exceeding both

supplies with no resulting phase inversion on the output.

The absolute maximum input voltage at V

+ = 3V is 300 mV

beyond either supply rail at room temperature. Voltages

greatly exceeding this absolute maximum rating, as in

Figure

2, can cause excessive current to flow in or out of the input

pins, possibly affecting reliability. The input current can be

externally limited to ±5 mA, with an input resistor, as shown

Figure 3.
