ZERO_CROSSING_DETECTOR_1

Published:2009/7/5 22:38:00 Author:May | From:SeekIC

This detector is useful in sine wave squaring circuits and A/D converters. The positive input may either ve grounded or connected to a nulling voltage which cancels input offsets and enables accuracy to within microvolts of ground. The CMOS output will switch to within a few millivolts of either rail for an input voltage change of less than 200 μV.
