SUCCESS!? Thanks, guys, I got it working with Universal Op Amp 2.?? It's working as it should.
?
I'm using simple transient analysis.?? The whole circuit consist of? one op amp and three voltage sources:? Supply is += 12V, Sine is 6 V 1000 Hz, reference is 3 VDC.? Simple and clean as I know how to make things.
?
As hoped and expected, Universal Op Amp 2 outputs a square wave triggered at the intersections of the sine wave and DC reference voltage. Square wave is 0-12 V when the op amp negative power supply is grounded, and it's -12 to +12 V when the op amp negative power supply is -12 V.??
?
However, substituting the MAX9095 for Universal Op Amp 2 still outputs a straight line, regardless of what the negative power terminal is connected to.? I chose the MAX9095 from the comparator list.? That makes me think I shouldn't need to include a library.? Is that what might be missing?
