2. Parameter guaranteed by design or characterization, not production tested.
3. Applies to both bipolar and unipolar input ranges.
4. These errors can be removed by re-calibrating at the desired operating temperature.
5. Applies after system calibration.
6. Fully differential input signal source is used.
7. See Load Test Circuit, Figure 10, R1 = 10kΩ, C
