Voltage Reference Procurement Notes

Verify the specific ordering suffix EIN8 corresponds to the Industrial temperature grade (-40°C to 85°C) and the 8-lead PDIP package configuration. Confirm the part marking matches the specified temperature and parametric grades as identified on the shipping container. Ensure compatibility with lead-free finish requirements if applicable to the assembly process.

Voltage Reference Selection Notes

Select this variant when an industrial temperature range is required alongside a 5V output. The EIN8 designation indicates the specific accuracy and thermal performance tier for this package type. Consider the minimum input-output differential of 0.9V when designing the power supply headroom. Evaluate the 20mA sourcing capability against the load requirements to ensure adequate drive strength.
