LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers
August 2000
LM124/LM224/LM324/LM2902
Low Power Quad Operational Amplifiers
General Description
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 sup-
ply current drain is independent of the magnitude of the
power supply voltage.
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 sys-
tems. For example, the LM124 series can be directly oper-
ated 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.
Advantages
n Eliminates need for dual supplies
n Four internally compensated op amps in a single
package
n Allows directly sensing near GND and V OUT also goes
to GND
n Compatible with all forms of logic
n Power drain suitable for battery operation
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 ± 1.5V to ± 16V
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
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
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
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 resis-
tance 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 de-
rated 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 am-
plifier 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 tran-
sistors 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).

with V + from 5V to 30V; and over the full input common-mode range (0V to V + − 1.5V) for LM2902, V + from 5V to 26V.
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 outputso
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.
Note 12: Refer to RETS124AX for LM124A military specifications and refer to RETS124X for LM124 military specifications.
