LM4040D82IDBZR

Overview

The LM4040D82IDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 8.192V with a maximum initial accuracy of 1.0% and a temperature coefficient of 150ppm/°C. The device operates within an ambient temperature range of -40°C to 85°C and requires a typical minimum cathode current of 45µA. Packaged in a space-saving SOT-23-3 format, it features low dynamic impedance and wideband noise characteristics suitable for portable applications.

Feature Summary

Stable with all capacitive loads without requiring an external output capacitor
Low dynamic impedance and low noise for stable performance across operating currents
Fuse and Zener-zap reverse breakdown voltage trim ensures tight output tolerances

Applications

Data-Acquisition Systems
Energy Infrastructure
Analog Input Module
Field Transmitters
Precision Audio

Procurement Notes

Verify the specific ordering suffix 'DBZR' corresponds to the SOT-23 package and tape-and-reel delivery method as defined in the manufacturer's Package Option Addendum. Confirm that the D-grade specifications align with project requirements for 1.0% tolerance and 150ppm/°C temperature coefficient before finalizing procurement.

Selection Notes

Select this component when a fixed 8.192V reference is required in a compact surface-mount footprint. The D-grade offers a cost-effective solution for applications where 1.0% accuracy and 150ppm/°C stability are sufficient. Ensure the design accommodates the minimum operating current of 45µA and the maximum cathode current limits specified in the electrical characteristics.

Part Context

This part belongs to the LM4040 series of precision micropower shunt voltage references from Texas Instruments. The series includes A, B, C, and D grades offering varying levels of accuracy and temperature stability. The LM4040D82IDBZR specifically represents the D-grade variant with an 8.192V output, designed for industrial temperature ranges and portable electronics.
