Technical content
Low Power Quad Operational Amplifiers ■ Wide gain bandwidth: 1.3MHz ■ Input common-mode voltage range includes ground ■ Large voltage gain: 100dB ■ Very low supply current/ampli: 375 µA ■ Low input bias current: 20nA ■ Low input offset voltage: 5mV max. (for more accurate applications, use the equivalent parts LM124A-LM224A-LM324A which feature 3mV max.) ■ Low input offset current: 2nA ■ Wide power supply range: Single supply: +3V to +30V Dual supplies: ±1.5V to ±15V
Description
These circuits consist of four independent, high gain, internally frequency compensated operational amplifiers. They 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.

1 Absolute Maximum Ratings
Table 1. 15Key parameters and their absolute maximum ratings
- Either or both input voltages must not exceed the magnitude of V CC
- Short-circuits from the output to VCC can cause excessive heating if V CC > 15V. The maximum output current
simultaneous short-circuit on all amplifiers.
- This input current only exists when the voltage at any of the input leads is driven negative. It is due to the
for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.
- Human body model, 100pF discharged through a 1.5k Ω resistor into pin of device.
- Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with
no external series resistor (internal resistor < 5 Ω), into pin to pin of device.

3 Electrical Characteristics
Table 2. V CC
100 V/mV
- The direction of the input current is out of the IC. This current is essentially constant, independent of the state
of the output so no loading change exists on the input lines.
- The input common-mode voltage of either input signal voltage should not be allowed to go negative by more
- Due to the proximity of external components insure that coupling is not originating via stray capacitance

LM124-LM224-LM324 Macromodels
5 Macromodels
Note: Note: Please consider following remarks before using this macromodel: All models are a trade-off between accuracy and complexity (i.e. simulation time). Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the NOMINAL performance of a TYPICAL device within SPECIFIED OPERATING CONDITIONS (i.e. temperature, supply voltage, etc.). Thus the macromodel is often not as exhaustive as the datasheet, its goal is to illustrate the main parameters of the product. Data issued from macromodels used outside of its specified conditions (Vcc, Temperature, etc.) or even worse: outside of the device operating conditions (Vcc, Vicm, etc.) are not reliable in any way.
