LM224DR

Overview

The LM224DR is a quad general-purpose operational amplifier manufactured by 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 specifications include an input offset voltage of 5 mV, input bias current of 150 nA, and a common-mode rejection ratio of 80 dB. Each channel provides an output current capability of 20 mA with a quiescent current of 1.4 mA per channel.

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 direct interfacing with standard logic levels.
• Features rail-to-rail output swing characteristics that maximize dynamic range in low-voltage applications.

Applications

• Transducer amplification for sensor signal conditioning
• DC gain blocks in measurement circuits
• Active filtering stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and electrical tolerances. Ensure the selected variant matches the required operating temperature range and packaging format for your assembly process. Cross-reference the component marking code with official identification guides to prevent counterfeit substitution during sourcing.

Selection Notes

Select this component when a cost-effective quad amplifier is required for general-purpose analog signal processing. It serves as a suitable alternative to the LM324 series where extended temperature performance down to -25°C is necessary. Consider the input offset voltage and bias current specifications relative to your application's precision requirements before finalizing the design.

Part Context

This part belongs to the LMx24 family of quad operational amplifiers produced by Texas Instruments. It shares architectural similarities with the LM324 but offers improved temperature stability and specific electrical parameter variations. The DR suffix indicates a tape-and-reel packaging configuration designed for automated surface-mount assembly processes.

Replacement Considerations

LM224DRG4 is a verified equivalent variant within the same product line.
