LM124/LM224/LM324/LM2902  
Low Power Quad Operational Amplifiers  
General Description  
Advantages  
n Eliminates need for dual supplies  
The LM124 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.  
n Four internally compensated op amps in a single  
package  
n Allows directly sensing near GND and VOUT also goes  
to GND  
n Compatible with all forms of logic  
n Power drain suitable for battery operation  
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 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.  
Features  
n Internally frequency compensated for unity gain  
n Large DC voltage gain 100 dB  
n Wide bandwidth (unity gain) 1 MHz  
(temperature compensated)  
n Wide power supply range:  
Single supply 3V to 32V  
or dual supplies  
n Very low supply current drain (700 µA)essentially  
independent of supply voltage  
n Low input biasing current 45 nA  
(temperature compensated)  
n Low input offset voltage 2 mV  
1.5V to 16V  
Unique Characteristics  
n 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  
n The unity gain cross frequency is temperature  
compensated  
and offset current: 5 nA  
n Input common-mode voltage range includes ground  
n Differential input voltage range equal to the power  
supply voltage  
n Large output voltage swing 0V to V+ − 1.5V  
n The input bias current is also temperature compensated

Note 4: For operating at high temperatures, the LM324/LM324A/LM2902 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/LM224A and LM124/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.  
+
Note 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.  
Note 6: 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).  
Note 7: These specifications are limited to −55˚C T +125˚C for the LM124/LM124A. With the LM224/LM224A, all temperature specifications are limited to  
A
−25˚C T +85˚C, the LM324/LM324A temperature specifications are limited to 0˚C T +70˚C, and the LM2902 specifications are limited to −40˚C T ≤

S
Note 9: 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.  
Note 10: 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), independent of the magnitude  
+
of V .  
Note 11: 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.

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.  
Application Hints  
The LM124 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 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.  
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).  
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.  
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 result-  
ing forward diode within the IC could cause fusing of the  
internal conductors and result in a destroyed unit.  
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.  
Large differential input voltages can be easily accommo-  
dated and, as input differential voltage protection diodes are  
not needed, no large input currents result from large differ-  
ential input voltages. The differential input voltage may be  
larger than V+ without damaging the device. Protection

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.  
Application Hints (Continued)  
The bias network of the LM124 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  
.
The circuits presented in the section on typical 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, introduc-  
ing 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.  
Output short circuits either to ground or to the positive power  
supply should be of short time duration. Units can be de-  
stroyed, not as a result of the short circuit current causing  
metal fusing, but rather due to the large increase in IC chip

sive 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 pro-  
tected with external dissipation limiting resistors in series  
with the output leads of the amplifiers. The larger value of
