Note 1:
This parameter is guaranteed by characterization and not 100% tested.
2:
See graph that relates linearity performance to V
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.
