Looking through the output range specification, I noticed a large number for
2kΩ load and ±15V supply. Why is that?
The built in short-circuit current-limit for the AD8422 output varies with
temperature as shown in Figure 32 of the data sheet. Most impactfully, the
positive (sourcing) limit decreases as the temperature gets colder. Figure 36
shows the effect this has on the output swing vs load resistance. This limit
can vary slightly from part-to-part, which was accounted for in the
