Note 1: Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity
performance, especially at elevated temperatures.
2: The time for the holding capacitor to acquire the âNewâ input voltage when the voltage changes full scale
after the conversion (VDD to VSS or VSS to VDD).
3: On the following cycle of the device clock.
