Well, that was a waste of time. I got it to work, but the Lite version only optimizes one variable at a time, for one measurement at a time, and doesn't really optimize, it just picks 5 points at random and tells you which is best? Looks like the commercial version is extremely expensive, so...
Ok, thanks. Newer version in C:\OrCAD\OrCAD_16.6_Lite\doc\pspaugca\pspaugca.pdf
Yes, 16.6 Lite.
Is that the same as C:\OrCAD\OrCAD_16.6_Lite\tools\pspice\tutorial\capture\pspiceaa\rfamp ? I don't have anything else named rfamp.
Edit:
Ah, that example from the tutorial doesn't work...
I'd like these too, or at least guidance on how to derive them from the datasheets. I found a bunch of 2SK parts, but not the 2 we're interested in: **broken link removed**
Honestly, I don't understand this circuit. I don't know if that's because the circuit's wrong or because it's just unfamiliar to me, but if that's just a normal op-amp, it looks like you have no negative feedback at all, so the op-amp's just running at full tilt and acting like a comparator...
Why do you have to adjust the level? If a water drop triggers it, then a balloon popping will trigger it, too. You're just checking for an event, not recording the sound.
This looks wrong to me, too, and the current version on the site (Rev B) still has this in it. Has anyone talked to the author?
The EIN for the op-amp is 1.131 µV, meaning an output noise of 100x: 113.1 µV.
The thermal noise of a 100 kΩ resistor is 5.7 µV, but don't you have to multiply that...

The C-Media USB audio chips I've seen (CM108, CM119, CM6300) actually don't block DC, which is why I'm going to use them for the same purpose. A simple, convenient way to get DC or low-freq measurements into a computer.
You can figure out the maximum and...
