To a DC signal, the input resistance is extremely high. The input signal is buffered by an operational amplifier buffer circuit with typically 1013 ohms resistance. There are a couple of ceramic caps that may contribute some leakage, but it's likely that it would be under 1uA and negligible, unless the voltage source had a very high source resistance.
