Features
Description
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.
