Overview

The LM324N/NOPB is a cost-effective quad operational amplifier package containing four independent, high-gain, internally frequency-compensated op-amps. It is specifically designed to operate from a single power supply over a wide range of voltages, with an input common-mode range that includes ground.

Why Choose This Part

The primary advantage is the ability to operate from a single supply while maintaining an input common-mode range that includes ground, eliminating the need for a negative power rail. Its 14-PDIP package is highly practical for through-hole prototyping and provides four amplifiers in a single footprint to reduce component count.

Applications

Transducer Amplifiers
Ideal for amplifying low-level signals from sensors where the input needs to sense near the ground rail.
DC Gain Blocks
Used in general-purpose analog signal processing circuits requiring high DC voltage gain up to 100 dB.
Battery-Powered Instrumentation
The low supply current of 0.7mA at 5V makes it suitable for portable equipment with limited power budgets.
Analog Filtering
Commonly implemented in active filter designs for industrial control systems and consumer electronics.

Getting Started

To use the LM324N, ensure your supply voltage is within the wide operating range and note that the output can swing to ground even with a single supply. For prototyping, it fits directly into standard 0.1-inch pitch breadboards. Always bypass the VCC pin with a 0.1uF ceramic capacitor near the IC to minimize noise.
