Note 1: This parameter is guaranteed by characterization and not 100% tested.
2: See graph that relates linearity performance to VREF level.
3: Because the sample cap will eventually lose charge, effective clock rates below 10kHz can affect linearity
performance, especially at elevated temperatures. See Section 6.2 for more information.
