Key Features
- Quad op-amp in compact SOIC package — four independent amplifiers in one Small Outline Package, saving board space and reducing component count
- Ultra-low supply current — designed for low-power applications with minimal quiescent current per amplifier
- Wide common-mode input range — operates down to ground on a single supply, simplifying single-supply circuit design
- High CMRR of 85 dB typical — excellent noise rejection for precision signal conditioning and sensing applications
- Voltage-feedback architecture with internal frequency compensation — stable in unity-gain configuration without external components
Applications
The LM324MX/NOPB is widely used in industrial and consumer electronics for signal conditioning, active filtering, and sensor interface circuits. Its single-supply, ground-referenced input makes it ideal for battery-powered instrumentation, comparator circuits, and audio pre-amplification. It also serves well in automotive and home-appliance control systems where low power consumption and quad-channel integration are critical.

Frequently Asked Questions
What are the key electrical specifications of the LM324MX/NOPB?
The LM324MX/NOPB features a maximum input bias current of 0.25 µA at 25 °C, a minimum common-mode rejection ratio of 65 dB (85 dB typical), and voltage-feedback architecture with internal frequency compensation. It operates from a single or dual supply and contains four independent op-amp channels in a Small Outline Package.
What are the typical applications for the LM324MX/NOPB?
Typical applications include active low-pass, band-pass, and high-pass filters, transducer amplifiers, DC gain blocks, and comparator circuits. Its ability to operate from a single supply down to ground makes it well suited for battery-powered devices, automotive control modules, sensor signal conditioning, and general-purpose audio amplification stages.
What package does the LM324MX/NOPB use and is it RoHS compliant?
The LM324MX/NOPB is housed in a Small Outline (SOIC) package, which is suitable for surface-mount assembly. The '/NOPB' suffix indicates it is lead-free and fully RoHS compliant, as confirmed by the 'Pbfree Code: Yes' specification. This makes it compatible with modern green manufacturing processes.
How does the LM324MX/NOPB compare to alternative quad op-amps?
Compared to alternatives such as the LM2902 or TL074, the LM324MX/NOPB offers a proven, cost-effective solution introduced in 1989 with broad second-source availability. Its 43-parameter characterization, low bias current, and high CMRR make it a reliable drop-in for designs requiring a general-purpose quad amplifier in an SOIC footprint.
