Parameters
This parameter is established by characterization and not 100% tested.
See graphs that relate linearity performance to V
Because the sample cap will eventually lose charge, effective clock rates below 10 kHz can affect linearity
performance, particularly at elevated temperatures. See Section 6.2 “Maintaining Minimum Clock
Speed”, “Maintaining Minimum Clock Speed”, for more information.
