Amplifiers — Manufactured by STMicroelectronics

The LM124/LM224/LM324 series consists of four independent, high-gain, internally frequency-compensated operational amplifiers. These devices are designed to operate from a single power supply over a wide voltage range, though they also support split-supply configurations. A key advantage is their low power consumption, which remains independent of the supply voltage magnitude. They are widely used in general-purpose signal conditioning and amplification applications due to their versatility and robust input common-mode range.
