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 âMaintaining Minimum Clock Speedâ for more information.
