NOTES:
4. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
5. All typical values have been characterized but not tested.
6. See “Parameters Definition” section.
7. Count is equal to one number change in the least significant digit of the display.
8. Parameter not tested on a production basis, guaranteed by design and/or characterization.
9. See “Differential Input” section.
