Don Symes	Re: Op amp input level Depends on the power rails and the gain setting. You can take the inputs to within a few millivolts of the rails on good, modern op-amps. Older, junky ones like the 741 can't get closer than a couple of volts. The next consideration is the gain. You can't get the output to swing beyond some specific point, so it's easy to get the output to clip if you set the gain too hihg. Sorry, but you'll have to convert these ravings to dB... I juszt can't keep that straight. Good luck!
