LM4040DIZ-4.1/NOPB

Overview

The LM4040DIZ-4.1/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed output of 4.1V. It operates within an industrial temperature range of -40°C to +85°C and offers an initial accuracy of ±1%. The device utilizes a SOT-23 package with three pins, supporting a maximum shunt current of 15mA and a minimum operating current of 60µA. Its temperature coefficient is specified at 150ppm/°C, ensuring stable performance across varying thermal conditions for analog circuit applications.

Feature Summary

Provides a fixed 4.1V reference voltage with ±1% initial accuracy
Operates as a micropower shunt regulator with low quiescent current
Designed for surface-mount installation in compact SOT-23 packages

Applications

Portable instrumentation requiring precise voltage references
Battery-powered measurement systems
Data acquisition circuits

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) rather than the extended automotive grade. Confirm the 'Z' designation aligns with current RoHS compliance standards. Ensure the ordering part number matches the exact voltage tolerance and package type required for your schematic design before finalizing procurement.

Selection Notes

Select this component when a fixed 4.1V reference is needed with ±1% accuracy in a small footprint. It is suitable for applications where power consumption must be minimized due to its micropower characteristics. Consider the 150ppm/°C temperature coefficient for thermal stability requirements within the industrial range.

Part Context

This part belongs to the LM4040 series of precision micropower shunt voltage references. The series is known for offering various fixed voltage options in compact packages. The LM4040DIZ variant specifically targets industrial environments, providing reliable performance without the higher cost or specifications associated with automotive-grade counterparts.
