Other Parts Discussed in Thread: OPA1637
I want to run a true differential circuit (e.g., using OPA1637 diff amp), with a differential input and differential output. I want to measure with diff output parameters using PSPICE.
What's the correct way to configure true differential AC Source waveform? Do I use TWO independent Sources with some kind of polarity flip on one of the Sources? Do I use a single source driving from both ends? Do I use the OPA1637 reference design (see attached) which uses functional blocks that I'm not familiar with? The OPA1637 reference design seems to be driven from identical polarities (not 180/180 differential). And while we're here, what's the correct way to measure a true differential output?
