MP Posted March 30, 2005 Report Share Posted March 30, 2005 There is nothing wrong with the circuit. If you look at the data sheet you will see why. The + and - markings on the schematic are mis labeled. Breadboarding the circuit shows that it will work.MPEnd of Topic. Alun's improved circuit has been moved to a new topic.

MP Posted April 2, 2005 Report Share Posted April 2, 2005 MOERATOR'S NOTE:The + and - markings have been fixed on the schematic on this site.The Bill of Materials now lists the IC as a comparator, not an op-amp.If you have built this circuit and used the bill of materials and pinout of the schematic, you would not have noticed anything wrong. If you are going to build this circuit, please disregard the earlier posts since the problems noted no longer exist.MP Link to comment Share on other sites More sharing options...
