Overview
The LM224ADT is a low-power, quad operational amplifier produced by STMicroelectronics. It consists of four independent, high-gain operational amplifiers with internal frequency compensation. These amplifiers 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 is independent of the magnitude of the power supply voltage, making it efficient for various applications.
