LM224KN

Overview

The LM224KN is a quad operational amplifier from the Texas Instruments LM224 series, housed in a 14-pin CDIP package. It features four independent high-gain frequency-compensated amplifiers designed for single-supply operation ranging from 3 V to 32 V, or dual supplies of ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 500 mV/µs, and an input offset voltage of 5 mV. The device draws a typical supply current of 1.4 mA and supports an output current of 20 mA per channel with a common-mode rejection ratio of 80 dB.

Feature Summary

• Four independent high-gain frequency-compensated operational amplifiers integrated into a single unit
• Designed specifically for stable operation using a single power supply source
• Low supply-current drain that remains independent of the magnitude of the applied supply voltage

Applications

• Transducer signal amplification
• DC amplification blocks
• Single-supply operational amplifier circuits

Procurement Notes

Verify the specific suffix 'KN' against official Texas Instruments documentation to confirm pinout compatibility and exact package dimensions. Ensure the component meets required environmental specifications for the intended operating temperature range. Cross-reference datasheet revisions to confirm electrical characteristics match design requirements before finalizing procurement.

Selection Notes

Select this component when a quad amplifier configuration is required for single-supply systems. It serves as a direct replacement for other LM224 variants within the same family, provided the package style matches the board layout. Consider the 1.2 MHz bandwidth and 500 mV/µs slew rate for applications requiring moderate speed and low power consumption.

Part Context

This part belongs to the LM224 family of low-power quad operational amplifiers manufactured by Texas Instruments. The family includes variants such as LM224J and LM224KADR, which share similar electrical performance but differ in packaging and termination styles. The LM224 series is widely used in general-purpose analog signal processing applications.

Replacement Considerations

LM224J (CDIP-14), LM224KAD (SOIC-14). Verify package compatibility for direct substitution.
