*Notice: Stresses above those listed under “Maximum ratings” may

cause permanent damage to the device. This is a stress rating only and

functional operation of the device at those or any other conditions

above those indicated in the operational listings of this specification is

not implied. Exposure to maximum rating conditions for extended peri-

ods may affect device reliability.

Note 1:

This parameter is established by characterization and not 100% tested.

2:

See graph that relates linearity performance to V

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 for more information.
