Notes:
1. tcal is the temperature at which calibration adjustment took place.
Maximum inductance for stability LCOMP OFF is 100 μH. Maximum inductance for stability LCOMP ON is 400 μH for 2 A and 20 A
ranges. 100 μH on the 120 A range.
With LCOMP ON, the output is limited to 7.2e3 A-Hz. For example, a 100 A output is limited to 72 Hz.
