DIGITAL INPUT AND OUTPUT CHARACTERISTICS
(AV DD = +5V, DV DD = DRV DD = +3.3V, T A = T MIN to T MAX , unless otherwise noted. Typical values are at T A = +25°C.)
Note 1: Reference inputs driven by operational amplifiers for Kelvin-sensed operation.
Note 2: For unipolar mode, the analog input voltage, V INP , must be within 0V and V REF , V INN = V REF /2; where V REF = V RFPS -
V RFNS . For differential mode, the analog input voltages V INP and V INN must be within 0V and V REF ; where V REF = V RFPS -
V RFNS . The common-mode voltage of the inputs INP and INN is V REF /2.
Note 3: Minimum and maximum parameters are not tested. Guaranteed by design.
Note 4: Input resistance 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.
