LM329AZ#PBF

Overview

The LM329AZ#PBF is a temperature-compensated 6.9V Zener voltage reference manufactured by Analog Devices Inc. It operates within a commercial temperature range of 0°C to 70°C and utilizes a buried Zener design for low noise. The device guarantees a maximum temperature coefficient of 10ppm/°C, a dynamic impedance of 1Ω, and wideband noise of 20µV. It supports an operating current range from 0.6mA to 15mA with a reverse-breakdown voltage typically at 6.9V.

Feature Summary

Temperature compensated 6.9V Zener reference providing excellent stability over time and temperature
Low dynamic impedance achieved through a high gain shunt regulator around the Zener
Low noise performance utilizing a buried Zener design that eliminates surface noise phenomena

Applications

Transducers
A/D and D/A Converters
Calibration Standards
Instrumentation Reference

Procurement Notes

Verify the specific suffix AZ corresponds to the 10ppm/°C grade and TO-92 package as documented in the ordering information table. Confirm lead-free finish status and ensure the component meets RoHS requirements before integration into production designs.

Selection Notes

Select this part when a stable 6.9V reference is required with strict limits on temperature drift and noise. The TO-92 package suits through-hole applications where space allows. Ensure the circuit maintains current between 0.6mA and 15mA for optimal regulation and stability characteristics.

Part Context

This component belongs to the LM329 series of precision voltage references. It shares the core buried Zener architecture with other grades like LM329BZ and LM329CZ but offers tighter temperature coefficient specifications. The series serves as a foundational reference element for analog signal conditioning circuits.
