LM224KDRG4

Overview

The LM224KDRG4 is a quad operational amplifier from Texas Instruments, 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 5 mV, input bias current of 150 nA, and a common-mode rejection ratio of 80 dB. It delivers 20 mA per channel output current with a quiescent current of 1.4 mA. 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 compact SOIC-14 package for space-constrained designs.
• Supports wide single-supply operation from 3 V to 32 V, enabling compatibility with standard logic levels and battery-powered systems.
• Features rail-to-rail input capability, allowing signal processing near the negative supply rail without saturation.

Applications

• General-purpose analog signal conditioning circuits
• Sensor interface applications requiring single-supply operation
• Industrial control systems utilizing standard voltage rails

Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and green material status. Ensure the ordering quantity matches the manufacturer's standard packaging specifications, typically available in cut tape or reel formats. Cross-reference the specific revision level if strict historical consistency is required for legacy production lines.

Selection Notes

Select this component when a quad amplifier configuration is necessary alongside wide single-supply voltage tolerance. The 1.2 MHz bandwidth suits low-frequency signal processing tasks. Consider the 5 mV input offset voltage specification for precision requirements. Verify that the 14-SOIC footprint aligns with existing PCB layout constraints and thermal management strategies.

Part Context

This device belongs to the LMx24 family of quad operational amplifiers manufactured by Texas Instruments. It shares architectural similarities with the LM124, LM224, and LM324 series, differing primarily in temperature rating and manufacturing revisions. The G4 suffix indicates a lead-free, RoHS-compliant variant produced under updated environmental standards compared to earlier NOPB or DR versions.

FAQ

Does the LM224KDRG4 support rail-to-rail output?

No, the datasheet specifies rail-to-rail input capability only; the output swing does not reach the positive supply rail.

What is the maximum supply voltage for this component?

The maximum total supply voltage is 32 V for single-supply operation or ±16 V for dual-supply configurations.
