1. Full scale input range, V
2. Input current is due to energy transferred to the input at the start of the sample period. The average value is dependent on input and V DD
3. The CLK input is a CMOS inverter with a 50k feedback resistor. It operates from the V
4. Parameter not tested, but guaranteed by design or characterization.
