LM399AH#PBF

Overview

The LM399AH#PBF is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 6.95V with an initial accuracy tolerance of ±0.17%. The device operates within a temperature range of 0°C to 70°C and features a low temperature coefficient of 1ppm/°C. Electrical characteristics include a noise level of 7µVrms measured between 10Hz and 10kHz, and a maximum cathode current of 10mA. The component is housed in a TO-46-4 metal can package designed for through-hole mounting.

Feature Summary

Provides high stability over wide ranges of voltage, temperature, and operating current conditions
Features excellent temperature stability suitable for standard cell replacement applications
Utilizes a TO-46-4 metal can package for robust physical protection

Applications

Standard cell replacement circuits
Precision voltage reference systems
High-stability measurement instrumentation

Procurement Notes

Verify the specific suffix AH against official Analog Devices documentation to confirm the exact grade and specifications. Ensure the TO-46-4 through-hole package matches the target PCB layout requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a stable 6.95V reference is required with minimal drift over varying environmental conditions. The TO-46-4 package necessitates through-hole assembly capabilities. Consider the 10mA maximum current limit and 1ppm/°C temperature coefficient when designing circuits demanding high precision without active thermal management.

Part Context

This part belongs to the LM399 family of precision shunt voltage references produced by Analog Devices Inc. The LM399 series is engineered for applications requiring superior long-term stability and low noise compared to standard zener diodes. The AH suffix typically denotes a specific performance grade within the broader product line.
