ST LM124W LM224W - LM324W LOW POWER QUAD OPERATIONAL AMPLIFIERS handbook
Datasheet
The LM224W is a high gain, low current, internally frequency compensated operational amplifier. It operates from a single power supply over a wide range of voltages. The LM224W can also be operated from split power supplies and the low power supply current drain is independent of the magnitude of the power supply voltage. All the pins are protected against electrostatic discharge up to 2000V.
