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: The CPIN value depends on the device package and is not tested. The effect of CPIN is negligible if Rs ï£ 5 kï.
