Overview
The LM324N is a quadruple operational amplifier (op-amp) from Texas Instruments (TI). This internal-frequency-compensated op-amp is designed to operate from a single power supply over a wide range of voltages or from dual supplies. It features large DC voltage gain, wide bandwidth, and a low power supply current drain, making it suitable for various applications, including battery operation.
