Note 1: Reference inputs driven by operational amplifiers for Kelvin-sensed operation.

Note 3: Minimum and maximum parameters are not tested. Guaranteed by design.

Note 5: Calibration remains valid for temperature changes within ±20°C and power-supply variations ±5%.

Note 6: All AC specifications are shown for the differential mode.
