  • 2: See graphs that relate linearity performance to V REF levels.

3: Because the sample cap will eventually lose charge, effective clock rates below 10 kHz can affect linearity performance, particularly at elevated temperatures. See Section 6.2 'Maintaining Minimum Clock Speed' , 'Maintaining Minimum Clock Speed', for more information.

†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 operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
