LM224NG4

Overview

The LM224NG4 is a quad operational amplifier manufactured by Texas Instruments, belonging to the LM224 series. It features four independent high-gain amplifiers with internal frequency compensation. The device operates on a single power supply ranging from 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 500 mV/µs, and an input offset voltage of 5 mV. It draws 1.4 mA of operating current per amplifier and provides a 20 mA output current per channel. The component utilizes a 14-pin CDIP package and supports through-hole mounting.

Feature Summary

• Quad configuration with four independent high-gain operational amplifiers
• Internal frequency compensation for stability
• Single or dual power supply operation capability
• Rail-to-rail input common-mode voltage range including ground

Applications

• General-purpose analog signal processing circuits
• DC gain blocks in instrumentation systems
• Active filter designs requiring low power consumption
• Transducer amplification interfaces

Procurement Notes

Verify the specific suffix 'NG4' against official Texas Instruments documentation to confirm pinout compatibility and package type. Ensure the procurement source provides valid RoHS compliance data as indicated by the G4 suffix. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when a quad op-amp solution is required with low power consumption and wide single-supply voltage tolerance. The LM224NG4 is suitable for applications where rail-to-rail input performance near ground is necessary but full rail-to-rail output swing is not critical. Consider the CDIP package constraints for PCB layout if through-hole assembly is mandated.

Part Context

This part belongs to the LM224 family of low-power quad operational amplifiers. It shares functional similarities with the LM124 and LM324 series but offers specific performance characteristics tailored for general-purpose applications. The LM224 variant typically denotes military or extended temperature grade components within the broader LMx24 lineage, providing robust performance across varying environmental conditions.
