DESCRIPTION/ORDERING INFORMATION
The
LM392
consists
of
internally-frequency-compensated operational amplifier, and the other is a precision voltage comparator. Both the
operational amplifier and the voltage comparator are designed to operate from a single power supply over a wide
range of voltages. Both circuits have input stages that force the common-mode input down to ground when
operating from a single power supply. Operation from split power supplies also is possible, and the low
power-supply current is independent of the magnitude of the supply voltage.
Applications include transducer amplifiers with pulse shapers, DC gain blocks with level detectors, and VCOs, as
well as all conventional operational amplifier or voltage-comparator circuits. The LM392 can be operated directly
from the standard 5-V power-supply voltage used in digital systems, and the output of the comparator interfaces
directly with either TTL or CMOS logic. In addition, the low-power drain makes the LM392 extremely useful in the
design of portable equipment.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
