I've been trying to figure out a design someone made for controlling a precision high current LED, and it's got me in a bit of a pickle. For the life of me, I can't figure out this exact op amp circuit config:
The shunt used looks like it's configured incorrectly as well.
I need to adjust the circuit to match a new LED.
I found these links helpful for getting a partial understanding:
Can someone help me understand what's going on here? R9 and the intended application lead me to believe this is set up as a constant current sink but I'm royally confused. Thanks for your help :)
