The LM392M is a dual low power high gain internally frequency compensated Operational Amplifier and Voltage Comparator specifically designed to operate from a single power supply over a wide range of voltages. Both circuits have input stages which will common-mode 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. Both circuits can be operated directly from the standard 5VDC power supply voltage used in digital systems and the output of the comparator will interface directly with either TTL or CMOS logic.
