Product Summary

The LM392M is a precision voltage comparator. It is specifically designed to operate from a single power supply over a wide range of voltages. The LM392M has input stages which will commonmode input down to ground when operating from a single power supply. Operation from split power supplies is also possible and the low power supply current is independent of the magnitude of the supply voltage. Application areas include transducer amplifier with pulse shaper, DC gain block with level detector, VCO, as well as all conventional operational amplifier or voltage comparator circuits. The LM392M can be operated directly from the standard 5 VDC power supply voltage used in digital systems, and the output of the comparator will interface directly with either TTL or CMOS logic. In addition, the low power drain makes the LM392M extremely useful in the design of portable equipment.
