Intro to Amplifier Comparator Circuits: LM311, LM393, LM2903 and LM2901
September 13th 2021 new story
In electronics, the comparator is a circuit that makes use of operational amplifiers with very high gain in its open-loop state. The **op-amp comparator** has a positive or negative voltage output by comparing its input voltage against some DC reference voltage. LM311 IC has been used for voltage comparisons for a long time in some typical circuits. LM393 and LM2903 are a kind of low offset voltage dual comparators, and their pin arrangement is shown in Figure 7. Their main performance is the same, but the temperature range is different: the former is 0\~70℃, and the latter is -40 ℃
