All current ranges from FOHx at full-scale current,
includes ±1 V dropped across sense resistor
External high current range at full-scale current, does
not include ±1 V dropped across sense resistor
Measured at midscale code; prior to calibration
Standard deviation = 20 μV/°C
Prior to calibration

Measure current = (IDUT × RSENSE × gain), amplifier
gain = 5 or 10, unless otherwise noted
Voltage across RSENSE; gain = 5 or 10
Measure current block with VREF = 5 V, MEASOUT

V(RSENSE) = ±1 V, measured with zero current flowing
Referred to MI input; standard deviation = 4 µV/°C
Using internal current ranges
Measure current amplifier alone
