LM329BZ#TRPBF

Overview

The LM329BZ#TRPBF is a temperature-compensated 6.9V Zener voltage reference manufactured by Analog Devices Inc. It utilizes a buried Zener design to achieve low dynamic impedance and excellent noise performance. The device operates within a current range of 0.6mA to 15mA and features a guaranteed maximum temperature coefficient of 10ppm/°C. It is housed in a 3-lead plastic TO-92 package and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

Guaranteed 10ppm/°C temperature coefficient for high stability
Maximum 1Ω dynamic impedance via high gain shunt regulator
Maximum 20µV wideband noise using buried Zener technology

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the B grade corresponds to the 10ppm/°C temperature coefficient specification required for your circuit design. Ensure the TO-92 package dimensions align with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select the LM329BZ#TRPBF when a stable 6.9V reference is needed with tight temperature drift requirements. The B grade ensures a maximum 10ppm/°C coefficient, superior to C or D grades. Consider the 0.6mA minimum operating current to ensure proper regulation during low-power system states.

Part Context

This component belongs to the LM329 series of precision voltage references from Analog Devices. It serves as a temperature-compensated shunt regulator designed for applications requiring high accuracy and low noise. The series includes various grades (A, B, C, D) offering different temperature coefficients to suit specific precision requirements.

Replacement Considerations

LM329CZ#TRPBF offers a 30ppm/°C coefficient. LM329DZ#TRPBF provides a 50ppm/°C coefficient. LM129 variants support extended industrial temperature ranges but are marked obsolete.
