Voltage Reference Procurement Notes

Verify the specific suffix IN8 indicates the PDIP-8 through-hole package variant distinct from surface-mount options. Confirm RoHS compliance status as listed in official documentation. Ensure the application circuit provides sufficient headroom above the minimum 6.5 V input requirement. Validate thermal management strategies for the operating environment. Check for any recent product change notifications affecting pinout or specifications.

Voltage Reference Selection Notes

Select this component when a fixed 5 V output is required with high accuracy and moderate load drive capabilities. Consider the PDIP-8 package for through-hole prototyping or manufacturing needs. Evaluate the 20 ppm/°C temperature coefficient against system stability requirements. Compare power consumption metrics if battery life is a critical design constraint. Verify compatibility with existing PCB layout constraints for the specified package type.
