LM124-LM224-LM324

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: 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.

LM124-LM224-LM324 5 Macromodels Note: Note: Please consider following remarks before using this macromodel: Macromodels 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.).
