Integrated Voltage Comparator Circuit

The integrated voltage comparator is a special operational amplifier. The operational amplifier is working in open-loop mode. Because its open-loop gain is bery big, the comparator's output is offen high voltage level or low voltage level. The integrated voltage comparator is a common signal processing unit circuit which is widely used in compare of signal amplitude and choice of signal amplitude and waveform transformation and shaping and so on. Some common integrated voltage comparator's pinout is shown in the picture. (a)Single Comparator LM311/CJ0311. (b)Double Comparator LM393. (c)High-Speed Comparator AD790. (d)Quatuor Comparator LM339/CJ-399.
