LM124W-LM224W-LM324W
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: 375µA
■ Low input bias current: 20nA
■ Low input offset voltage: 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.
All the pins are protected against electrostatic
discharges up to 2000V (as a consequence, the
input voltages must not exceed the magnitude of
VCC+ or VCC-.)

1. 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.
2. Vo = 1.4V, Rs = 0Ω, 5V < VCC+ < 30V, 0 < Vic < VCC+ - 1.5V
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more
than 0.3V. The upper end of the common-mode voltage range is VCC+ - 1.5V, but either or both inputs can go to
+32V without damage.
4. Due to the 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
frequences.

5 Macromodels
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.
