1 Temperature range: 40°C to +105°C; typical at +25°C.
2 Guaranteed by design and characterization; not production tested.
3 For current outputs with internal R
SET, the offset, full-scale, and TUE measurements exclude dc crosstalk. The measurements are made with all four channels enabled
and loaded with the same code.
