Overview
The LM124DT, produced by STMicroelectronics, is a low-power quad operational amplifier. It 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 LM124DT is known for its low supply current, low input bias current, and wide gain bandwidth, making it suitable for various applications in industrial, automotive, and consumer electronics.
