LM124 is a low power quad operational amplifier with high gain, low noise, low power consumption, wide operating voltage, and is widely used in instruments, instruments, communications, medical equipment and other fields.
This document provides technical specifications for the LM124, LM224, and LM324 series of low power quad operational amplifiers. Key features include a wide gain bandwidth product of 1.3MHz, input common-mode voltage range that includes ground, and very low supply current drain independent of the power supply magnitude.
The datasheet details absolute maximum ratings, electrical characteristics such as input offset voltage and bias current across different temperatures, and typical single-supply applications including AC coupled inverters, DC summing amplifiers, and instrumentation amplifiers. It also includes mechanical package data for DIP14, TSSOP14, and SO14 packages.
