APPLICATION INFORMATION
Input Common-Mode Voltage Range
The LMC6462/4 has a rail-to-rail input common-mode voltage range. Figure 33 shows an input voltage
exceeding both supplies with no resulting phase inversion on the output.
Figure 33. An Input Voltage Signal Exceeds the LMC6462/4 Power Supply Voltage with No Output Phase
Inversion
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 34, 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 35.
