• High-accuracy digital-to-analog converter (DAC) biasing
• Calibration equipment requiring stable voltage standards

Voltage Reference Procurement Notes

Verify the specific suffix LH against current manufacturer documentation to confirm availability status, as legacy parts may be discontinued or subject to limited supply constraints. Ensure the required tolerance and package type match the design specifications before ordering. Cross-reference with authorized distributors to confirm authenticity and handling requirements for sensitive electronic components.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V reference with ±0.4% initial accuracy is required. The series topology and TO-52-3 package make it suitable for applications needing robust physical construction. Consider thermal operating limits and input voltage headroom relative to the 40V maximum rating during system design.
