Voltage Reference Procurement Notes

Verify the specific B-grade accuracy and 20ppm/°C temperature coefficient requirements against your design specifications. Confirm that the 8-lead LS8 hermetic package dimensions align with your PCB layout constraints. Ensure proper handling procedures are followed due to the ceramic package type. Cross-reference the datasheet electrical characteristics for load regulation and noise parameters relevant to your circuit topology.

Voltage Reference Selection Notes

Select this component when a stable, low-drift reference is required in harsh environments. The LS8 package offers superior stability compared to plastic packages. Consider the 20ppm/°C drift if tighter tolerance is not needed. Verify input voltage headroom relative to the 2.048V output. Evaluate the need for automotive qualification if applicable, as other suffixes may be required.
