Overview
The LM324QT is a quad operational amplifier produced by STMicroelectronics. It is part of the LM324 family, which consists of four independent, high-gain operational amplifiers with internal frequency compensation. This device operates 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 LM324QT is packaged in a QFN-16L package, making it suitable for a variety of applications requiring compact design and low power consumption.
