I'm off to the Shack; I need an amplifier to convert an AC signal (maybe 20kHz or more, ±<200mV) to clock pulses for counting on a 4017. I know that the LM393 will work, but I think the TL082 may be a bit faster and that could be better for my application.
The LM393 datasheet says it has a response time of 1.3µs, whereas the TL082 datasheet says it has a slew rate of 13V/µs. I'm using a single 5V supply (maybe 9v soon), so I believe the TL082 will switch a bit faster than the LM393, maybe under 1µs?
Any advice or comments? I may just buy and try both of them.
