 		 #56566 - RE: OP-AMP, Porportional Voltage adjustm
Responding to: ???'s previous message
I am controling a DC motor that operates 5-50VDC at a max 5A. Right now, I use a manual pot to drive the darlington Transitor which set how much power the motor gets. I need to be able to adjust the power 0 -50VDC. I would prefer to use a digital pot
