LM4040D41IDBZRG4

Overview

The LM4040D41IDBZRG4 is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed output voltage of 4.096V. It belongs to the D grade, offering a maximum initial accuracy of ±1% and a temperature coefficient of 150ppm/°C. The device operates within an ambient temperature range of –40°C to 85°C and is housed in a space-saving SOT-23-3 package. It requires a minimum cathode current of 45μA (typical) and supports a maximum operating current of 15mA.

Feature Summary

Provides stable reference voltage with low dynamic impedance and low noise characteristics
Operates without external capacitors and remains stable with all capacitive loads
Utilizes fuse and Zener-zap reverse breakdown voltage trim for precise tolerance control

Applications

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

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per the manufacturer's documentation. Confirm the 'I' designation corresponds to the industrial temperature range (-40°C to 85°C). Ensure the ordering part number matches the exact voltage and package requirements for your design.

Selection Notes

Select this component when a 4.096V reference with ±1% initial accuracy is required. It is suitable for applications needing low power consumption with a typical operating current of 45μA. Consider the 150ppm/°C temperature coefficient for thermal stability requirements within the specified industrial temperature range.
