The LM124/124A is a low power quad operational amplifier produced by Texas Instruments. It has the characteristics of high gain, internal frequency compensation and can be powered by a single power supply or split power supply. The product is widely used in transducer amplifiers, DC gain blocks and various conventional op amp circuits.
The LM124A/LM124QML family consists of four independent, high‑gain, internally frequency‑compensated operational amplifiers designed for single‑supply operation over a wide voltage range. They feature low supply current, ground‑referenced input common‑mode range, and are suitable for transducer amplifiers, DC gain blocks and other conventional op‑amp circuits.
