Legend: CPIN = Input Capacitance
VT
= Threshold Voltage
ILEAKAGE = Leakage Current at the pin due to
various junctions
RIC
= Interconnect Resistance
RSS = Sampling Switch Resistance
CHOLD = Sample/Hold Capacitance (from DAC)
Note: CPIN value depends on the device package and is not tested. The effect of CPIN IS negligible if Rs  5 k.
