I'm getting ready to order some junk from Digikey. Can someonerecommend good general purpose op-amps to stock for tinkering? I'vebeen using the 741 just because I had a few laying around, but I knowthat better things exist. I've also got a couple of TL082s, but reallyhaven't done much of anything with them yet. The 741 has worked ok(more or less) for me, but I want something with better gain at 40kHz(ultrasound tinkerings) and that can go much closer to the rails since Ilike to use 5V for power. Something that won't easily latch up would benice too. I don't need anything really fancy, just something relativelyinexpensive ($2 or so) and easy to use. BTW, I like to use solderlessbreadboards for prototyping.For comparators I use the LM393, is that still a reasonable choice orshould I stock up on something newer?TIA
