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
in Figure 3
