I'm trying to turn the analog output from a circuit (the rectified voltage from a current transformer, 0v to 1v or so) into a HIGH/LOW (0v, 3.3v) signal for my raspberry pi. I think this can be done with a voltage comparator. I read an article about doing this with an IC741 voltage comparator. But I can't find that part on ebay, I can only find UA741 op amps. Is that the same thing?
I've built simple circuits, and and am now starting to wrap my head around op amps. Can any op amp be used as a voltage comparator?
Thanks
