Overview
The LM224QT, produced by STMicroelectronics, is part of the LM124, LM224x, and LM324x family of low-power quad operational amplifiers. These devices consist of four independent, high-gain operational amplifiers with internal frequency compensation. They are designed to operate from a single power supply over a wide range of voltages (3 V to 30 V) and can also operate from split power supplies (±1.5 V to ±15 V). The low-power supply current drain is independent of the magnitude of the power supply voltage, making them versatile for various applications.
