00 — Overview

What the LM324ADR family does

The UMW LM324 is a quadruple operational amplifier featuring four independent, internally frequency compensated amplifiers. It operates from a single power supply over a wide voltage range, with variants available for commercial and industrial temperature grades. Key parameters include a DC voltage gain of 100 V/mV, a common-mode input voltage range equal to the supply voltage, and a low supply current drain independent of the supply magnitude. The device is typically used in transducer amplifiers, DC gain blocks, and all conventional op amp circuits. It supports split power supplies and handles differential input voltages up to the power supply voltage.
