Parameter Sym Min Typ Max Units Conditions
Note 1: This parameter is established by characterization and not 100% tested.
2: See graphs that relate linearity performance to V
REF
levels.
3: Because the sample cap will eventually lose charge, effective clock rates below 10 kHz can affect linearity
performance, especially at elevated temperatures. See Section 6.2 “Maintaining Minimum Clock
Speed”, “Maintaining Minimum Clock Speed”, for more information.
