I would really appreciate some help from someone kind with a moment to spare for a ignorant novice.
I am designing a circuit that takes a variable 0-5V, 20ma voltage from a D-A converter controlled by my computer called a LabJack and turn it into a proportional 0-8V 2A output to power an hydraulic solenoid for a flight simulator. The catch is the DA signal should be isolated to protect the expensive LabJack and I have a 12V+ regulated power supply to use. (I can get a hold of a 12V+, 12V- if I must).
A very kind gentleman made a circuit up for me (see attached) but I keep blowing the expensive UA741s trying to get it to work...Should I somehow switch the circuit to 12V+ and 12V- ???
Thank you
