Parameter Sym Min. Typ. Max. Units Conditions
Note 1: This parameter is established by characterization and not 100% tested.
2: 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” for more information.
