The Current-Controlled Resistor is a resistor that varies either logarithmically or linearly between specified values of a controlling input current.

If LIMIT is disabled, the input is not internally limited. Therefore, if the controlling signal exceeds the specified VOFF state or VON state value, the resistance may become excessively large or excessively small (in the case of logarithmic dependance), or may become negative (in the case of linear dependance).


Parameter Description Units Default
ION Control current for RON value. A 1
IOFF Control current for ROFF value. A 0
RON Resistance value when the control current is VON. ohm 1
ROFF Resistance value when the control current is VOFF. ohm 1e9
LOG Logarithmic or linear resistor.   Log
LIMIT Limits the control current between VON and VOFF.   Yes
