LM392/LM2924
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 volt-
age comparator. Both the operational amplifier and the volt-
age comparator have been specifically designed to operate
from a single power supply over a wide range of voltages.
Both circuits have input stages which will common-mode in-
put down to ground when operating from a single power sup-
ply. Operation from split power supplies is also possible and
the low power supply current is independent of the magni-
tude 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
DC 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 LM392 extremely useful in the design of portable
equipment.
