Procurement Notes

Verify the manufacturer origin as National Semiconductor has been acquired by Texas Instruments. Ensure the part number matches the specific suffix for the MX package type. Confirm RoHS compliance status if required for your assembly process. Check for any obsolescence notices from the current manufacturer regarding this specific component.

Selection Notes

Select this component when dual op-amps with rail-to-rail I/O are needed in a small SOIC-8 package. Consider the LM358 or TLV2372 as alternatives if different pinouts or performance metrics are acceptable. Evaluate the supply voltage requirements against the application's available power rails. Verify the temperature range meets the environmental conditions of the final product.

Part Context

This component belongs to the LMx02 series of dual operational amplifiers. It is designed for general-purpose analog signal processing tasks. The MX suffix indicates a surface-mount SOIC-8 package. It is commonly used in consumer electronics and industrial control systems where space and power efficiency are critical constraints.

Replacement Considerations

Check for direct pin-compatible replacements such as the LM358N or TLV2372IDR. Verify electrical parameters like slew rate and bandwidth match the original design requirements. Ensure the replacement package type is compatible with the existing PCB footprint.
