Product overview
Description
The LM124, LM224x and LM324x consist of four independent, high gain operational amplifiers with frequency compensation implemented internally. 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.
-
