Procurement Notes

Verify the manufacturer designation as Rochester Electronics, which sustains legacy parts. Confirm the specific suffix (A or B) matches your design requirements. Check for RoHS compliance status as these are legacy components. Ensure the package type aligns with your PCB footprint. Validate the date code and lot traceability if required for your quality standards.

Selection Notes

Select this component when fast settling and wideband performance are critical in low-gain applications. Compare specifications against other wideband op-amps if higher gain stability is needed. Consider the package constraints and thermal management requirements. Verify supply availability through authorized distributors specializing in legacy semiconductors. Ensure the operating temperature range meets your environmental conditions.

Part Context

This part belongs to the CLC400 series of fast-settling operational amplifiers. Originally developed by National Semiconductor, it was designed for video and high-speed analog applications. Rochester Electronics provides continued production for obsolete or end-of-life parts, ensuring long-term availability for industrial and commercial products that depend on this specific amplifier technology.

Replacement Considerations

Direct replacements may include the CLC400AJM5 or similar variants from the same family. Verify pinout compatibility before substitution. Check if alternative manufacturers offer equivalent fast-settling amplifiers. Ensure that any substitute meets the original bandwidth and settling time requirements. Consult official datasheets for detailed parameter comparisons.
