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

Note 2: For unipolar mode, the analog input voltage, VINP, must be within 0 and VREF, VINN = VCM / 2; where VREF = VRFPS - VRFNS.

For differential mode, the analog input voltages VINP and VINN must be within 0 and VREF; where VREF = VRFPS - VRFNS. The

common-mode voltage of the inputs INP and INN is VCM = (VRFPS + VRFNS) / 2.

Note 3: RI varies inversely with sample rate.

Note 4: 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%. Guaranteed by design.

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