AD2702SD

Voltage Reference Overview

The AD2702SD/883B is a hermetically sealed, two-output three-terminal voltage reference housed in a ceramic DIP-14 package with bottom brazing. It provides a nominal output of 10 V, with a range from 9.995 V to 10.005 V. The device operates within a temperature range of -55 °C to +125 °C and contains 14 terminals.

Voltage Reference Feature Summary

• Hermetically sealed ceramic construction for environmental stability
• Dual output capability within a single three-terminal reference architecture
• Bottom brazed mounting for secure mechanical attachment

Voltage Reference Applications

• Military radar systems requiring stable reference voltages
• Secure communications equipment
• High-reliability instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix /883B indicates compliance with MIL-PRF-38534 or equivalent military standards. Confirm lead times and availability directly with authorized distributors or Rochester Electronics, as this is a specialized aerospace component. Ensure handling procedures account for the hermetic ceramic package.

Voltage Reference Selection Notes

Select this component when high reliability and radiation hardness are required alongside precise voltage referencing. The ceramic DIP-14 package suits applications needing robust thermal management and mechanical durability in harsh environments compared to standard plastic packages.

Voltage Reference Part Context

This part belongs to the AD2702 precision voltage reference series by Analog Devices. It is distributed by Rochester Electronics, which specializes in obsolete and hard-to-find components. The /883B designation typically denotes military-grade screening and packaging requirements.

Voltage Reference Replacement Considerations

Check for direct equivalents such as AD2702 variants with different suffixes. Verify pin compatibility and electrical specifications before substituting with other hermetic references.
