Hi,
i want to make Voltage to Current converting, but not linear, i need it ExpLog.
0-5V is the Control Voltage for Input to the OPV.
Output is like an LED with breakdown voltage 2-4V and its have a treshold current, example 50-200mA
Now i want the 0-5V translate it to "treshold current" -> 1A
If 0V then treshold current goes to 0mA and if 0,1V then start treshold Current and makes it exponetial function to the max values.
Any idea ?
