Hi,
I am trying to build a circuit to convert a voltage into a 4 - 20mA signal
Basically I have a POT in which the voltage divider provides between 0.8 and 4.6V from a 5V supply (or 1.2 to 2.2KOhm impedance) and I want to convert that into a 4 - 20mA signal.
Any advice?
PS: No my pot wont go all the way down to zero.
Range of values is 1230 to 2200Ohm.
Many Thanks
