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 0V and VREF, VINN = VREF / 2; where VREF = VRFPS - VRFNS.

For differential mode, the analog inputs INP and INN must be within 0V and VREF; where VREF = VRFPS - VRFNS. The com-

mon mode of the inputs INP and INN is VREF / 2.

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

Note 4: RI varies inversely with sample rate.

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.
