Overview
The LM324AN/NOPB is a low-power quad operational amplifier produced by Texas Instruments. It is part of the LM124-N series, which includes four independent, high-gain, internally frequency-compensated operational amplifiers. These amplifiers are designed to operate from a single power supply over a wide range of voltages, making them versatile for various applications. The LM324AN/NOPB can also operate from split-power supplies and features a low-power supply current drain that is independent of the magnitude of the power supply voltage.
