LM169H

Overview

The LM169H is a precision monolithic voltage reference based on buried zener technology, featuring a built-in temperature stabilizer. It provides a fixed output voltage of 10V with a maximum supply current of 50 mA. The device operates within an extended temperature range from -55°C to 125°C and is housed in a TO-99-8 metal can package.

Feature Summary

• Utilizes buried zener reference architecture for high stability
• Includes integrated temperature stabilization circuitry
• Constructed in a hermetic metal can package

Applications

• High-precision analog signal conditioning
• Calibration standards requiring stable voltage sources
• Military and aerospace instrumentation systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm lot traceability and military qualification requirements if applicable. Inspect physical integrity of the TO-99-8 package upon receipt. Ensure storage conditions meet specified humidity and temperature limits to preserve performance characteristics.

Selection Notes

Select this component when a fixed 10V reference with extreme temperature stability is required. Consider the TO-99-8 package constraints for board layout. Evaluate thermal management needs given the 50 mA supply current. Verify compatibility with existing system voltage ranges and interface requirements before integration.

Part Context

Part of the National Semiconductor LM169/LM369 family of precision voltage references. Shares core buried zener technology with the LM199 series but offers different output voltage configurations. Designed for applications demanding superior long-term stability and low noise compared to standard bandgap references.
