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
