DESCRIPTION
•
Very Low Supply Current Drain (700
μA)—Essentially Independent of Supply
Voltage
The LM124-N series consists of four independent,
high gain, internally frequency compensated
operational amplifiers which were designed
specifically to operate from a single power supply
over a wide range of voltages. Operation from split
power supplies is also possible and the low power
supply current drain is independent of the magnitude
of the power supply voltage.
•
•
Low Input Biasing Current 45 nA (Temperature
Compensated)
Low Input Offset Voltage 2 mV
–
and Offset Current: 5 nA
•
•
•
Input Common-Mode Voltage Range Includes
Ground
Application areas include transducer amplifiers, DC
gain blocks and all the conventional op amp circuits
which now can be more easily implemented in single
power supply systems. For example, the LM124-N
series can be directly operated off of the standard
+5V power supply voltage which is used in digital
systems and will easily provide the required interface
electronics without requiring the additional ±15V
power supplies.
Differential Input Voltage Range Equal to the
Power Supply Voltage
Large Output Voltage Swing 0V to V+ − 1.5V
UNIQUE CHARACTERISTICS
•
In the Linear Mode the Input Common-Mode
Voltage Range Includes Ground and the
Output Voltage can also Swing to Ground,
Even Though Operated from Only a Single
Power Supply Voltage
•
•
The Unity Gain Cross Frequency is
Temperature Compensated
The Input Bias Current is also Temperature
Compensated

(3) This input current will only exist 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 IC chip. This transistor action can cause the output voltages of the op amps 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 will re-establish when the input voltage, which was negative, again returns to a value greater than −0.3V (at 25°C).
(4) For operating at high temperatures, the LM324-N/LM324A/LM2902-N must be derated based on a +125°C maximum junction
temperature and a thermal resistance of 88°C/W which applies for the device soldered in a printed circuit board, operating in a still air
ambient. The LM224-N/LM224A and LM124-N/LM124A can be derated based on a +150°C maximum junction temperature. The
dissipation is the total of all four amplifiers—use external resistors, where possible, to allow the amplifier to saturate of to reduce the
power which is dissipated in the integrated circuit.
(5) 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 independent of the magnitude of V+. At values of supply voltage in excess of +15V,
continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result
from simultaneous shorts on all amplifiers.

(1) These specifications are limited to −55°C ≤ TA ≤ +125°C for the LM124-N/LM124A. With the LM224-N/LM224A, all temperature
specifications are limited to −25°C ≤ TA ≤ +85°C, the LM324-N/LM324A temperature specifications are limited to 0°C ≤ TA ≤ +70°C, and

O ≃ 1.4V, RS = 0Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+ − 1.5V) for LM2902-N, V+ from 5V to
26V.
(3) The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the
state of the output so no loading change exists on the input lines.
(4) The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The
upper end of the common-mode voltage range is V+ − 1.5V (at 25°C), but either or both inputs can go to +32V without damage (+26V
for LM2902-N), independent of the magnitude of V+.
(5) Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This
typically can be detected as this type of capacitance increases at higher frequencies.
(6) 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 independent of the magnitude of V+. At values of supply voltage in excess of +15V,
continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result
from simultaneous shorts on all amplifiers.

APPLICATION HINTS
The LM124-N series are op amps which operate with only a single power supply voltage, have true-differential
inputs, and remain in the linear mode with an input common-mode voltage of 0 VDC. These amplifiers operate
over a wide range of power supply voltage with little change in performance characteristics. At 25°C amplifier
operation is possible down to a minimum supply voltage of 2.3 VDC
.
The pinouts of the package have been designed to simplify PC board layouts. Inverting inputs are adjacent to
outputs for all of the amplifiers and the outputs have also been placed at the corners of the package (pins 1, 7, 8,
and 14).
Precautions should be taken to insure that the power supply for the integrated circuit never becomes reversed in
polarity or that the unit is not inadvertently installed backwards in a test socket as an unlimited current surge
through the resulting forward diode within the IC could cause fusing of the internal conductors and result in a
destroyed unit.
Large differential input voltages can be easily accommodated and, as input differential voltage protection diodes
are not needed, no large input currents result from large differential input voltages. The differential input voltage
may be larger than V+ without damaging the device. Protection should be provided to prevent the input voltages
from going negative more than −0.3 VDC (at 25°C). An input clamp diode with a resistor to the IC input terminal
can be used.
To reduce the power supply drain, the amplifiers have a class A output stage for small signal levels which
converts to class B in a large signal mode. This allows the amplifiers to both source and sink large output
currents. Therefore both NPN and PNP external current boost transistors can be used to extend the power
capability of the basic amplifiers. The output voltage needs to raise approximately 1 diode drop above ground to
bias the on-chip vertical PNP transistor for output current sinking applications.
For ac applications, where the load is capacitively coupled to the output of the amplifier, a resistor should be
used, from the output of the amplifier to ground to increase the class A bias current and prevent crossover
distortion.
Where the load is directly coupled, as in dc applications, there is no crossover distortion.
Capacitive loads which are applied directly to the output of the amplifier reduce the loop stability margin. Values
of 50 pF can be accommodated using the worst-case non-inverting unity gain connection. Large closed loop
gains or resistive isolation should be used if larger load capacitance must be driven by the amplifier.
The bias network of the LM124-N establishes a drain current which is independent of the magnitude of the power
supply voltage over the range of from 3 VDC to 30 VDC
.
Output short circuits either to ground or to the positive power supply should be of short time duration. Units can
be destroyed, not as a result of the short circuit current causing metal fusing, but rather due to the large increase
in IC chip dissipation which will cause eventual failure due to excessive junction temperatures. Putting direct
short-circuits on more than one amplifier at a time will increase the total IC power dissipation to destructive
levels, if not properly protected with external dissipation limiting resistors in series with the output leads of the
amplifiers. The larger value of output source current which is available at 25°C provides a larger output current
capability at elevated temperatures (see TYPICAL PERFORMANCE CHARACTERISTICS) than a standard IC
op amp.
The circuits presented in the section on Typical Single-Supply Applications emphasize operation on only a single
power supply voltage. If complementary power supplies are available, all of the standard op amp circuits can be
used. In general, introducing a pseudo-ground (a bias voltage reference of V+/2) will allow operation above and
below this value in single power supply systems. Many application circuits are shown which take advantage of
the wide input common-mode voltage range which includes ground. In most cases, input biasing is not required
and input voltages which range to ground can easily be accommodated.
