Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: 1LSB = 0.0015% of full scale = 15.3ppm of full scale.
Note 3: Using internal feedback resistor.
Note 4: Guaranteed by design, not subject to test.
Note 5: I
Note 6: Typical temperature coefficient is 100ppm/C.
Note 7: OUT1 load = 100 in parallel with 13pF.
