Note 1:
This parameter is established by characterization and not 100% tested.
2:
See graphs that relate linearity performance to VREF levels.
3:
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
, “Maintaining Minimum Clock Speed”, for more information.
