LM324N TI Quadruple Amplifier Low Power Wide Supply (Pack of 5)

Description

Product Overview

The LM324N from Texas Instruments is a versatile quad operational amplifier packaged in a convenient 14‑pin DIP format, making it ideal for both prototype breadboarding and production assembly. Each of the four independent amplifiers is designed with high gain and internal frequency compensation, ensuring stable performance across a broad range of applications. The device operates from a single supply voltage as low as 3 V or from dual supplies ranging from ±1.5 V to ±16 V, giving designers flexibility in power budgeting and system architecture. With a typical supply current of only 0.8 mA per amplifier, the LM324N delivers excellent efficiency, which is especially valuable in battery‑operated or energy‑constrained designs. Input bias currents are exceptionally low, typically 20 nA, and input offset voltage is around 3 mV, providing accurate signal amplification with minimal error. The common‑mode input range includes ground, allowing direct sensing of signals that sit at or near ground potential without the need for additional level‑shifting circuitry. The differential input voltage range matches the maximum rated supply voltage, up to 32 V, giving the part a wide dynamic range for handling large signal swings.

Usage

Engineers and hobbyists alike find the LM324N well‑suited for a variety of signal‑conditioning tasks. In industrial environments, it can be employed in sensor interface circuits, such as temperature, pressure, and light sensors, where its low offset and bias currents help preserve measurement fidelity. The wide supply voltage range enables use in both low‑voltage microcontroller systems and higher‑voltage control panels, making it a flexible choice for mixed‑signal designs. In portable equipment, the low quiescent current extends battery life, while the ability to operate from a single supply simplifies board layout and reduces component count. Audio pre‑amplifier stages benefit from the LM324N’s low noise and high gain, delivering clean amplification for microphones and line‑level sources. Additionally, the part is frequently used in comparator circuits, active filters, and instrumentation amplifiers, where its stable frequency response and robust input range provide reliable operation under demanding conditions.
