Applications
The LM224DRG3 is widely used in industrial signal conditioning circuits, where its quad op-amp configuration enables multi-channel amplification in a single package. It is well suited for sensor interface boards, active filter designs, and instrumentation amplifiers operating across extended industrial temperature ranges. Its low bias current and high CMRR also make it a popular choice in precision analog front-end circuits for data acquisition systems.

Frequently Asked Questions
What is the supply voltage range for the LM224DRG3?
The LM224DRG3 operates from a single supply of 3 V to 32 V or a dual supply of ±1.5 V to ±16 V, making it flexible for both battery-powered and industrial 24 V systems.
What are typical applications for the LM224DRG3?
The LM224DRG3 is commonly used in industrial sensor signal conditioning, active filters, instrumentation amplifiers, comparator circuits, and data acquisition analog front ends where four independent op-amp channels are needed in a compact Small Outline Package.
How does the LM224DRG3 compare to the LM324?
The LM224DRG3 is the industrial-grade version of the LM324 family, rated for –25°C to +85°C operation versus the commercial 0°C to 70°C range of standard LM324. Both share the same pinout and quad op-amp architecture with 70 dB minimum CMRR and 0.25 µA typical bias current.
What package does the LM224DRG3 come in?
The LM224DRG3 is available in a 14-pin Small Outline (SOIC) package (the 'DR' suffix), with tape-and-reel packaging ('G3' suffix) for automated pick-and-place assembly in high-volume production.
