mvs sarma Posted October 26, 2006 Report Share Posted October 26, 2006 Hiplease see any datashhet for LM324it an ic with four similar circuits called comparator.each one can compare two input signals and out put a +ve voltage or a near earth depending on the comaprision. this just in plain english approximately. for datails see the datasheet at sl No 12 athttp://www.electronics-lab.com/downloads/datasheets/ic_analog.htmlsarma Quote Link to comment Share on other sites More sharing options...
audioguru Posted October 26, 2006 Report Share Posted October 26, 2006 please see any datashhet for LM324it an ic with four similar circuits called comparator.No, Sarma.An LM324 has four opamps, not comparators.An opamp can have negative feedback applied to have any amount of closed-loop gain required. An opamp is fairly slow.A comparator cannot have negative feedback applied so is used with its full gain of about 200,000. A comparator is fairly fast.An opamp can be used as a fairly slow comparator. Quote Link to comment Share on other sites More sharing options...
