Notes:
4. 4.35 V to 5.25 V VCC.
5. Measured as largest step size vs nominal according to measured full scale and zero programmed values.
6. POR can occur only once per applied VCC, if VCC drops below Vrst, POR will not re-occur. VCC must return to 0.0V before POR will be re-applied on a subsequent
VCC ramp.
7. Low to High transition
8. This parameter is guaranteed, but not tested.
9. Tratio = Isink1(n)/Isink0(n) for the same n
10. Irange = Isink(F)/Isink(O) for port 0 or 1 output
