Procurement Notes

Verify the specific suffix 'CPN' against the official Analog Devices datasheet to confirm the package type and temperature range. Ensure the source document explicitly lists this part number variant, as suffixes may indicate distinct packaging or regional specifications. Cross-reference manufacturer identifiers to avoid confusion with similar Maxim Integrated references.

Selection Notes

Select the MAX620CPN when designing circuits requiring a stable 2.5 V reference with minimal drift over temperature. Its buried-zener architecture makes it suitable for applications demanding low noise without external filtering. Consider the 8-pin DIP package for prototyping or through-hole designs where surface-mount options are not feasible.
