LM224N

Overview

The LM224N is a quad operational amplifier from the Texas Instruments LinCMOS family, housed in a 14-pin DIP package. It features a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/µs. 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 bias current of 45 nA, an input offset voltage of 2 mV, and a common-mode rejection ratio of 80 dB. Each channel provides an output current capability of 40 mA.

Feature Summary

• Integrates four independent high-gain operational amplifiers within a single integrated circuit.
• Supports operation with single or split power supply voltages for flexible system integration.
• Features rail-to-rail input and output capabilities to maximize dynamic range.

Applications

• General-purpose analog signal conditioning circuits
• Transducer amplification interfaces
• DC gain blocks

Procurement Notes

Verify the specific suffix 'N' corresponds to the standard plastic DIP-14 package configuration. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the operating temperature range aligns with the -25°C to +85°C specification. Cross-reference pinout diagrams with the official datasheet to prevent socketing errors during assembly.

Selection Notes

Select this component when a quad amplifier topology is required for cost-sensitive designs. The 1 MHz bandwidth suits low-frequency applications where higher speeds are unnecessary. Consider the 40 mA output drive capability for direct interfacing with moderate loads without additional buffering stages.

Part Context

This part belongs to the LM224 series, which utilizes LinCMOS technology to achieve low power consumption while maintaining robust performance. It serves as a quad-channel variant within the broader LM124/LM224/LM324 family, offering standardized pinouts compatible with legacy designs requiring four amplifiers.
