LM324N Description

The LM324N by Texas Instruments is a general-purpose quad operational amplifier housed in a 14-pin DIP package, designed for through-hole mounting. Part of the LinCMOS™ series, it operates over a wide supply voltage range of 3V to 32V, making it highly versatile for both low and high-voltage applications. With four independent op-amps in a single package, it offers space-efficient solutions for multi-channel signal conditioning. The device features a 1.2 MHz gain bandwidth product, 45 nA input bias current, and 2 mV input offset voltage, ensuring reliable performance in precision analog circuits. Its low supply current (1.5mA) and 40 mA output current per channel further enhance efficiency and drive capability.
