LM4040BEM3-4.1+T

Overview

The LM4040BEM3-4.1+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 4.096V with an initial accuracy of ±0.2%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +125°C. It supports a wide operating current range from 60µA to 15mA and utilizes a 3-pin SOT23 surface-mount package.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy across multiple grades
Stable operation without requiring external stabilizing capacitors
Capable of tolerating any capacitive load on the output

Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process controls
Automotive systems

Procurement Notes

Verify that the specific part number matches the required electrical specifications, including the 4.096V output, 0.2% accuracy grade, and extended temperature range. Confirm the package type is SOT23-3 and check for lead-free/RoHS compliance indicated by the suffix. Ensure the ordering information aligns with the intended application requirements before finalizing procurement.

Selection Notes

Select this component when a stable, accurate reference voltage is needed in space-constrained designs. The B-grade offers a balance of precision and cost-effectiveness compared to higher accuracy grades. Consider the thermal resistance and power dissipation limits if operating near the upper temperature boundary or under high load currents.

Part Context

This component belongs to the LM4040 family of micropower shunt voltage references. The family includes various output voltages and accuracy grades (A, B, C, D) packaged in SC70 or SOT23 formats. The 'E' designation indicates the extended industrial temperature range capability, distinguishing it from standard industrial variants.

Replacement Considerations

LM4040BIM3-4.1+T is available as an alternative with the same electrical characteristics but operates over a limited temperature range (-40°C to +85°C). Verify that the reduced temperature range meets the environmental requirements of the target application.
