Voltage Reference Procurement Notes

Verify the manufacturer designation matches Maxim Integrated specifications for the LM4051 series. Confirm the suffix indicates tape and reel packaging and the specific 1.225V output variant. Ensure the SC-70 package dimensions align with board layout requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a low-cost, fixed 1.225V reference is required in a compact SC-70 footprint. The A-grade accuracy suits applications needing tighter tolerance than standard industrial grades. Consider the BICMOS process characteristics for compatibility with existing Maxim Integrated design ecosystems.

Voltage Reference Part Context

This part belongs to the LM4051 family of micropower shunt voltage references. It shares the core architecture with other variants like the LM4051BIX3-1.2 but differs in initial accuracy grading. The family is characterized by its small form factor and suitability for space-constrained electronic designs.

Voltage Reference Replacement Considerations

LM4051BIX3-1.2 offers similar functionality with potentially different accuracy grades.
