LM329CZ#PBF

Overview

The LM329CZ#PBF is a temperature-compensated 6.9V precision shunt voltage reference manufactured by Analog Devices Inc. It operates within a 0°C to +70°C range and utilizes a buried Zener design for low noise. Key electrical parameters include a nominal reverse-breakdown voltage of 6.9V (max 7.25V), a maximum dynamic impedance of 1Ω, and a guaranteed temperature coefficient of 30ppm/°C. The device supports an operating current range from 0.6mA to 15mA with a maximum wideband noise of 20µV.

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
Buried Zener design eliminates surface noise phenomenon associated with ordinary Zeners

Applications

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

Procurement Notes

Verify component authenticity against official Analog Devices documentation. Confirm package type matches TO-92-3 specifications. Ensure environmental compliance requirements align with RoHS standards. Check datasheet for absolute maximum ratings to prevent operational damage during integration.

Selection Notes

Select this part for applications requiring a stable 6.9V reference in industrial or instrumentation environments. The TO-92 package suits through-hole designs. Verify that the 30ppm/°C temperature coefficient meets system accuracy needs. Ensure supply voltage allows for sufficient headroom above the 6.9V breakdown voltage while staying within the 40V maximum limit.

Part Context

This component belongs to the LM329 series of precision voltage references. It is distinct from the LM129, which offers a wider -55°C to 125°C operating range. The LM329 family includes various grades (A, B, C, D) with different temperature coefficients. The #PBF suffix indicates a lead-free finish compliant with environmental directives.
