Electrical Performance Limits
Voltage compliance developed across inductive loads may prevent range maximum current output being achieved at
higher frequencies. The appropriate maximum frequency (F
max ) for a given load inductance and current is given by:
F max =
4.5 I = Current

•
L L = Total
inductance
The maximum frequency calculated with this equation is only approximate. Series resistance and parallel capacitance
also affect the maximum achievable frequency.
Input common mode rejection ............................. 80 dB @ DC decreasing linearly to 40 dB at 10 kHz
Input Impedance
Voltage input ....................................................... >1 M
Ω
Current input ....................................................... 10
Ω
Maximum output compliance voltage ................. 4.5 V rms (6.4 V pk), 6.4 V dc. 120 A range maximum compliance
voltage decreases from 4.5 V at 1 kHz to about 3 V at 10 kHz
DC Offset ............................................................... Magnetic remanence that follows abrupt changes in output current
level may cause small changes to DC current offset. It is good practice
to correct for offsets in DC measurements and techniques such as DC
reversal measurement will result in best accuracy.
