Overview
The LM324APT is a low-power, quad operational amplifier produced by STMicroelectronics. It consists of four independent, high-gain operational amplifiers with internal frequency compensation. These amplifiers can operate from a single power supply over a wide range of voltages (3 V to 30 V) or from dual supplies (±1.5 V to ±15 V), making them versatile for various applications. The low power supply current drain is independent of the magnitude of the power supply voltage, which is beneficial for power-efficient designs.
