The LM124, LM224 and LM324 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.
This document is a technical datasheet for the LM124, LM224, and LM324 low power quad operational amplifiers manufactured by STMicroelectronics. The devices consist of four independent, high gain, internally frequency-compensated operational amplifiers that operate from a single power supply over a wide range of voltages, from +3 V to +30 V, or split power supplies from ±1.5 V to ±15 V.
