@ |IOL| = 1.6 mA
@ | IOH| = 400 A
@ DUTGND = 0V, VSENSE = 5V
Temperature coefficients are valid over a 25˚C to 85˚C junction temperature range unless otherwise noted.
The mV/V units shown are derived as follows: ( offset current * range resistance) / output force voltage.
SELIPMU = SELEPMU = FV/FI = 0.
FI Gain =
MI Gain =
VCC – 6V is the maximum LLV voltage that will clamp
full-scale current on Range D. LLV will clamp
full-scale current for ranges A, B, and C all the way
up to HLV – 1V.
