*I did search and couldnt find much.*
I have a curcuit that is controllable by a pot (potentiometer).
It is approx .6V and at max resistance via the pot the current is ~40mA, and low resistance is ~140mA.
I want to try to use a digital Pot but most DigiPots I find are a max of 1mA continous and/or 20mA switching.
Is there ANY way to lower the amperage of this curcuit... even lowering it before the DigiPot and then raising it back after? I'm willing to spend 20-30 dollars if possible and can wire it up if I had a basic understanding of how it worked.
Thanks for your help
