LM224ADRE4

Overview

The LM224ADRE4 is a quad operational amplifier from the LM224A series, manufactured by Texas Instruments. It features four independent high-gain amplifiers in a 14-pin SOIC package. Key electrical parameters include a gain-bandwidth product of 1.2 MHz and a slew rate of 500 mV/us. The device operates on a single power supply ranging from 3 V to 32 V, or dual supplies from ±1.5 V to ±16 V. It draws 1.4 mA of operating current and provides 20 mA output current per channel. Input specifications include a maximum input offset voltage of 5 mV, input bias current of 150 nA, and a common-mode rejection ratio of 80 dB. The component supports rail-to-rail input operation and functions within a temperature range of -25°C to +85°C.

Feature Summary

• Integrates four independent high-gain operational amplifiers within a single compact package
• Supports single-supply operation with wide voltage range capability up to 32 V
• Features rail-to-rail input functionality for extended signal handling
• Designed for general-purpose applications with low power consumption characteristics

Applications

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

Procurement Notes

Verify the specific ordering suffix RE4 against the manufacturer's current datasheet to confirm compliance with RoHS directives and lead time requirements. Ensure the SOIC-14 package dimensions match the target PCB footprint. Confirm that the -25°C to +85°C industrial temperature range aligns with the system's environmental operating conditions before finalizing procurement.

Selection Notes

Select this component when a quad amplifier configuration is required with single-supply compatibility. The 1.2 MHz gain-bandwidth product suits applications not demanding high-speed performance. Compare the 5 mV input offset voltage against precision requirements. Consider the 14-SOIC package constraints for thermal management and board space availability relative to alternative packages like DIP or TSSOP.

Part Context

This part belongs to the LM224 family, which includes variants such as LM224AD and LM224ADR. The RE4 suffix typically denotes a specific tape-and-reel packaging format compliant with environmental standards. It shares core electrical characteristics with other LM224 variants but differs in packaging and potentially minor manufacturing revisions defined by the manufacturer.

Replacement Considerations

LM224ADR serves as a direct pin-compatible alternative with identical electrical specifications but may differ in packaging type. LM224AD offers the same circuitry in tube packaging. Verify that substitute parts maintain the same SOIC-14 footprint and temperature rating.
