*Notice: Stresses above those listed under “Maximum rat-

ings” 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. Expo-

sure to maximum rating conditions for extended periods may

affect device reliability.

Note 1: This specification is established by characterization and not 100% tested.

5: Maximum clock frequency specification must be met.

7: TSSOP devices are only specified at 25°C and +85°C.

8: For slow sample rates, see Section 6.2.1 for limitations on clock frequency.
