LM4040DIM7-2.5/NOPB

Overview

The LM4040DIM7-2.5/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a nominal output voltage of 2.5 V with an initial accuracy of 1%. It operates within a temperature range of -40°C to +85°C and utilizes an SC-70-5 surface-mount package. The device supports a maximum cathode current of 12 mA and maintains a minimum operating current of 100 µA. Its temperature coefficient is specified at 150 ppm/°C, ensuring stable performance across the industrial temperature range for precision analog applications.

Feature Summary

Provides a fixed 2.5 V precision reference output suitable for high-accuracy analog circuits
Operates in a wide industrial temperature range from -40°C to +85°C
Features low power consumption with a minimum operating current of 100 µA
Utilizes a compact SC-70-5 surface-mount package for space-constrained designs

Applications

Portable instrumentation requiring low power consumption
Battery-powered measurement systems
Data acquisition systems needing stable voltage references
Microcontroller supply monitoring circuits

Procurement Notes

Verify that the specific part number LM4040DIM7-2.5/NOPB matches the required SC-70-5 package and 2.5 V output specification. Confirm compliance with RoHS directives and check for any recent product change notifications regarding packaging or manufacturing site updates. Ensure the supplier provides valid traceability documentation for quality assurance purposes before finalizing procurement orders.

Selection Notes

Select this component when a 2.5 V precision reference is required in a small SC-70-5 footprint. It is appropriate for applications demanding 1% initial accuracy and operation up to 85°C. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements. Compare against other LM4040 variants if different packages or voltage outputs are needed.

Part Context

This device belongs to the LM4040-N family of micropower shunt voltage references from Texas Instruments. The family offers various fixed voltage options and package types, including SOT-23 and SC-70 formats. The LM4040 series is designed for general-purpose precision applications where low power and small size are critical constraints in electronic design.
