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 supply 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 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.

Unique Characteristics

nIn 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

nThe unity gain cross frequency is temperature compensated

nThe input bias current is also temperature compensated

Advantages

nEliminates need for dual supplies

nFour internally compensated op amps in a single package

nAllows directly sensing near GND and VOUT also goes to GND

nCompatible with all forms of logic

nPower 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

nVery low supply current drain (700 µA) Ð essentially independent of supply voltage

Note 4: For operating at high temperatures, the LM324/LM324A/LM2902 must be derated based on a +125ÊC maximum junction temperature and a thermal resistance of 88ÊC/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 +150ÊC maximum junction temperature. The dissipation is the total of all four amplifiers Ð 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 25ÊC).

Note 7: These specifications are limited to −55ÊC ≤ TA ≤ +125ÊC for the LM124/LM124A. With the LM224/LM224A, all temperature specifications are limited to −25ÊC ≤ TA ≤ +85ÊC, the LM324/LM324A temperature specifications are limited to 0ÊC ≤ TA ≤ +70ÊC, and the LM2902 specifications are limited to −40ÊC ≤ TA ≤ +85ÊC.

Note 8: VO 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, 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 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 25ÊC). The upper end of the

common-mode voltage range is V+ − 1.5V (at 25ÊC), 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.
