†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 periods
may affect device reliability.

level.
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” for more information.
