LM4040BEM3-4.1/V+T

Overview

The LM4040BEM3-4.1/V+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a maximum temperature coefficient of 100 ppm/°C. Key electrical parameters include a cathode current of 73 µA, a maximum shunt current of 15 mA, and a typical noise of 64 µVrms from 10 Hz to 10 kHz. It is housed in a compact SOT-23-3 package.

Feature Summary

Provides stable fixed output voltage over the industrial temperature range
Ultra-low operating current suitable for power-restricted designs
High precision with low initial tolerance and low noise characteristics

Applications

Portable instrumentation requiring low power consumption
Battery-powered measurement systems
Data acquisition systems needing precise voltage references

Procurement Notes

Verify the exact suffix 'V' against official manufacturer documentation, as standard listings typically use '+T'. Confirm RoHS compliance status and ensure the component matches the specified SOT-23-3 package dimensions. Cross-reference datasheet revisions to confirm pinout consistency before integration into production designs.

Selection Notes

Select this component when a 4.096 V reference with ±0.2% accuracy is required in a small surface-mount package. Consider the 100 ppm/°C temperature coefficient for thermal stability needs. Ensure the design accommodates the 73 µA minimum cathode current and up to 15 mA shunt current capability within the -40°C to +125°C operating range.

Part Context

This part belongs to the LM4040 family of two-terminal shunt mode bandgap voltage references. The family offers various fixed reverse breakdown voltages including 2.048 V, 2.5 V, 3.0 V, 3.3 V, 4.096 V, and 5.0 V. The 'B' designation indicates the ±0.2% accuracy grade, distinguishing it from other precision tiers in the series.
