Overview
The LM224PT, 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 LM224PT is packaged in a TSSOP-14 format, making it suitable for a variety of applications where space is a concern.
