The input voltage range extends from 200mV below (V-) to 200mV above (V+), maximizing input dynamic range. The input stage has ESD clamps to the (V+) supply line and therefore the input voltages must not exceed the supply voltages by more than 200mV. It is not recommended to apply signals to the rail to rail inputs with no supply voltage. To avoid damaging the inputs when exceeding the recommended input voltage range, an external resistor should be used to limit the current to less than 1mA.
