LM224ADRG4

Overview

The LM224ADRG4 is a quad operational amplifier manufactured by Texas Instruments, featuring four independent high-gain amplifiers within a single package. It operates with a supply voltage range of 3 V to 32 V or dual supplies from ±1.5 V to ±16 V. Key electrical specifications include a gain-bandwidth product of 1.2 MHz, a slew rate of 500 mV/µs, and an input offset voltage of 5 mV. The device draws 1.4 mA of operating current and provides 20 mA output current per channel. It utilizes a 14-SOIC surface-mount package and supports an industrial temperature range from -25°C to +85°C.

Feature Summary

• Integrates four independent high-gain operational amplifiers in a compact SOIC-14 package
• Supports wide single-supply (3 V to 32 V) and dual-supply operation
• Features rail-to-rail input capability for extended common-mode voltage range
• Designed for general-purpose applications with low power consumption

Applications

• General-purpose analog signal processing circuits
• Transducer amplification interfaces
• Active filter designs
• Voltage comparators and buffer stages

Procurement Notes

Verify the specific suffix 'G4' indicates compliance with RoHS directives and Green manufacturing standards as defined by Texas Instruments. Confirm the package type matches the required PCB footprint for the 14-SOIC variant. Ensure the temperature grade corresponds to the industrial range (-25°C to +85°C) required for the target application environment before finalizing procurement.

Selection Notes

Select this component when a quad amplifier configuration is required for cost-sensitive designs. The LM224ADRG4 offers a balance of moderate bandwidth and low quiescent current suitable for battery-powered systems. Consider the 5 mV input offset voltage specification for precision requirements. Verify that the 20 mA output drive capability meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the LMx24 family of quad operational amplifiers, which are industry-standard devices widely used in analog electronics. The 'A' designation typically denotes improved performance parameters compared to the base LM224 model, while 'DRG4' specifies the tape-and-reel packaging and environmental compliance. It serves as a direct replacement for legacy quad op-amp designs requiring surface-mount assembly.

Replacement Considerations

Compatible substitutes include LM224ADR and LM224DRE4 from Texas Instruments, which share identical pinouts and core electrical characteristics. Cross-manufacturer equivalents such as the MC174CDR from ON Semiconductor may be considered if pin compatibility and parameter tolerances align with the design specifications.
