Resistive Load See test conditions/comments column
Chosen such that compliance is not
exceeded
Inductive Load See test conditions/comments column
Needs appropriate capacitor at
higher inductance values; see the
Driving Inductive Loads section
Settling Time
4 mA to 20 mA, Full-Scale Step 8.5 μs 250 Ω load
4 mA to 20 mA Range, 120 μA Step 1.2 μs 250 Ω load
DC PSRR 1 μA/V
Output Impedance 130 MΩ
Leakage Current −12 +12 nA Output disabled; leakage to ground
VOUT/VSENSE− Error 0.9994 1.0006 Gain
Error in VOUT voltage due to changes
in VSENSE−; specified as gain, for
example, if VSENSE− moves by 1 V,
then VOUT moves by 0.9994 V
