*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 maxi-
mum rating conditions for extended periods may affect device
reliability.

Note 1: This parameter is guaranteed by characterization and not 100% tested.
2: See graph that relates linearity performance to V
REF
level.
3: Because the sample cap will eventually lose charge, clock rates below 10 kHz can affect linearity perfor-
mance, especially at elevated temperatures.
