1 Tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels.

2 Resistance value and absolute current outputs subject to 20% tolerance.

3 Specification assumes the external op amp is trimmed for negligible input offset.

4 Includes all errors.
