LM4040C25IDBZTG4

Overview

The LM4040C25IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.5%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 150 PPM/°C. It requires a minimum cathode current of 75 µA and supports a maximum shunt current of 15 mA. The component is housed in a SOT-23-3 surface-mount package.

Feature Summary

Provides stable 2.5 V reference voltage with 0.5% initial accuracy
Operates across extended industrial temperature range from -40°C to +125°C
Designed for low power consumption with micropower shunt architecture

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring precise voltage references
Handheld meters and test equipment

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm that the component is marked as Obsolete or End-of-Life, which may impact long-term supply availability. Ensure ordering quantities align with available packaging options such as cut tape or reel formats specified in official distributor listings.

Selection Notes

Select this component when a 2.5 V reference with 0.5% tolerance is required in a compact SOT-23-3 package. Consider the 150 PPM/°C temperature coefficient for thermal stability requirements. Verify that the system can accommodate the 75 µA minimum operating current and 15 mA maximum shunt current limits during design integration.

Part Context

This part belongs to the LM4040 series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The C25 designation specifically denotes the 2.5 V output variant with 0.5% initial accuracy, distinguishing it from other voltage levels and tolerance classes within the same family.
