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
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
