Note

1:

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

2: See characterization graphs that relate converter performance to V

5: Maximum clock frequency specification must be met.

6: V

7: MSOP 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.
