LM392

Low Power Operational Amplifier/Voltage Comparator

General Description

The LM392 series consists of 2 independent building block

circuits. One is a high gain, internally frequency compen-

sated operational amplifier, and the other is a precision

voltage comparator. Both the operational amplifier and the

voltage comparator have been specifically designed to op-

erate 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 cir-

cuits. Both circuits can be operated directly from the stan-

dard 5 V

and the output of the comparator will interface directly with

either TTL or CMOS logic. In addition, the low power drain

makes the LM392 extremely useful in the design of portable

equipment.
