Overview

Description

The LM324N is a quad operational amplifier (op-amp) integrated circuit designed for a wide range of analog applications. Featuring four independent, high-gain, internally frequency-compensated op-amps, the LM324N is suitable for single-supply and dual-supply voltage operations. It operates over a wide voltage range from 3V to 32V (or ±1.5V to ±16V for dual supplies), making it versatile for various power supply configurations.
Key features of the LM324N include low power consumption, a wide bandwidth of 1 MHz, low input bias current, and a high gain of 100 dB. It is commonly used in filtering, signal conditioning, and level shifting applications. Its ability to function effectively with a single power supply makes it ideal for battery-operated devices and applications where space and power efficiency are critical.
The LM324N is housed in a 14-pin dual in-line package (DIP), making it easy to use on breadboards and through-hole PCBs. Its robust design and reliable performance have made it a staple in analog circuit design.
