Procurement Notes

Verify the specific suffix 'EPA' corresponds to the required -40°C to +85°C operating temperature range and 8-pin Plastic DIP package. Confirm that the ordering code matches the exact electrical specifications for the 4.096V output variant. Ensure compliance with RoHS directives if applicable to the manufacturing batch. Cross-reference the manufacturer's latest documentation to confirm current availability status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when high-resolution data conversion systems require a stable reference with minimal drift. The buried-zener architecture ensures superior noise characteristics compared to standard bandgap references. Consider the external trim pin for applications demanding precise calibration beyond the factory-set accuracy. Verify that the input voltage range accommodates the system supply variations while maintaining optimal line regulation performance.

Part Context

The MAX6341 belongs to the MAX6325/MAX6341/MAX6350 family of precision voltage references from Maxim Integrated. This series shares identical packaging, pinouts, and core architectural features, differing primarily in their fixed output voltages. The MAX6341 specifically targets applications requiring a 4.096V reference, complementing the 2.5V and 5V variants within the same product line.
