DESCRIPTION/ORDERING INFORMATION
The
LM392
consists
of
two
independent
building-block
circuits.
One
is
a
high-gain
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.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) This input current exists only when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the
input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also
lateral NPN parasitic transistor action on the device. This transistor action can cause the output voltages of the amplifiers to go to the V+
voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive, and normal
output states reestablish when the input voltage, which was negative, again returns to a value greater than –0.3 V (at 25°C).
(3) Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground,
the maximum output current is approximately 40 mA for the operational amplifier and 30 mA for the comparator, independent of the
magnitude of V+. At values of supply voltage in excess of 15 V, continuous short circuits can exceed the power dissipation ratings and
cause eventual destruction.
(4) Package thermal impedance is calculated in accordance with JESD 51-7.

(1) The direction of the input current is out of the device due to the PNP input stage. This current essentially is constant and independent of
the state of the output, so no loading change exists on the input lines.
(2) The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end
of the common-mode voltage range is V+ – 1.5 V, but either or both inputs can go to 32 V without damage.
(3) Due to proximity of external components, ensure that coupling is not originating via the stray capacitance between these external parts.
This typically can be detected, as this type of capacitive coupling increases at higher frequencies.
(4) Positive excursions of input voltage may exceed the power-supply level. As long as the other input voltage remains within the
common-mode range, the comparator provides a proper output state. The input voltage to the operational amplifier should not exceed
the power-supply level. The input voltage state must not be less than –0.3 V (or 0.3 V below the magnitude of the negative power
supply, if used) on either amplifier.
