PARAMETER
CONDITION
MIN TYP
Reference Input Voltage Vref
VKA = Vref, IK = 10 mA, TA = 25°C (1)
VKA=Vref,IK=10 mA,TA= 0 to 70°C(1)
Vref temp deviation
Vdev VKA = Vref, IK = 10 mA ,(1) TA = full range
Ratio of change in Vref
to change in VKA
DVref IK = 10mA DVKA = 10V to Vref
DVKA
DVKA = 36V to 10V
Reference input current Iref IK = 10mA, R1 = 10KW, R2 = (2)
Deviation of reference
input current over full
Iref(dev) IK = 10mA, R1 = 10KW, R2 = (2)
