LM224KADRG4

Overview

The LM224KADRG4 is a quad operational amplifier from the Texas Instruments LM224 series, housed in a 14-SOIC surface-mount package. It features a gain-bandwidth product of 1.2 MHz and a slew rate of 500 mV/us. The device operates on a single supply voltage ranging from 3 V to 32 V or dual supplies from 1.5 V to 16 V. Key electrical parameters include an input offset voltage of 2 mV, input bias current of 15 nA, and a quiescent current of 1.4 mA per four channels. Each channel provides an output current capability of 30 mA with a common-mode rejection ratio of 80 dB.

Feature Summary

• Integrates four independent high-gain operational amplifiers within a compact 14-pin SOIC footprint.
• Supports wide single-supply operation up to 32 V or split dual-supply configurations.
• Delivers robust load drive capability with 30 mA output current per channel.

Applications

• Transducer amplification for sensor signal conditioning
• DC gain blocks in measurement circuits
• Audio frequency signal processing

Procurement Notes

Verify the specific suffix 'KADR' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the component meets RoHS3 standards as indicated by the 'G4' designation. Cross-reference the ordering part number with authorized distributors to validate authenticity and traceability before integration into production designs.

Selection Notes

Select this component when a quad amplifier configuration is required with a 14-SOIC package constraint. It is suitable for applications needing a 1.2 MHz bandwidth and 30 mA output drive. Consider the 2 mV input offset voltage specification for precision requirements. Verify that the 3 V to 32 V supply range aligns with the system power architecture.

Part Context

This part belongs to the LMx24 family of general-purpose operational amplifiers manufactured by Texas Instruments. The LM224 variant represents the military temperature grade (-25°C to 85°C) compared to the commercial LM124 and industrial LM324. The 'KADR' suffix denotes the specific tape-and-reel packaging format for automated assembly.
