As Richard has suggested, am I > reaching a slew-rate limit ? The LM358 will swing its outputs from 0V to V+ - 1.5V. So you can expect to see clipping at 3.5V if you have a 5V supply. Its input common mode range has the same limits. -- Ned Konz http://bike-nomad.com GPG key ID: BEEA7EFE -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
