Voltage Reference Procurement Notes

Verify the specific ordering suffix 'DC' confirms the 0.1% accuracy grade and 20ppm/°C temperature coefficient. Confirm the 'S8' designation matches the required 8-lead SOIC package type. Ensure the '#PBF' suffix indicates lead-free finish compliance. Validate that the component meets the specified commercial operating temperature range requirements.

Voltage Reference Selection Notes

Select this part when a fixed 2.5V reference with 0.1% accuracy is required in surface-mount packaging. Consider the 20ppm/°C drift specification for thermal stability needs. Evaluate the 165µA supply current against power budget constraints. Verify compatibility with the 3.4V to 20V input voltage range.
