LM4040BIM3-4.1+T

Overview

The LM4040BIM3-4.1+T is a precision micropower shunt 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 operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100ppm/°C. It utilizes a subminiature 3-pin SOT-23 surface-mount package, supports a shunt current range from 60μA to 15mA, and maintains stability without requiring external capacitors.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy across operating conditions.
Low dynamic impedance ensures stable reverse breakdown voltage over wide current ranges.
Inherently stable with any capacitive load, eliminating the need for external stabilizing capacitors.

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm the package type corresponds to the design footprint. Ensure the temperature grade aligns with the operational environment requirements. Check RoHS compliance status if mandated by project standards. Validate manufacturer authenticity through authorized distribution channels.

Selection Notes

Select this component when space constraints require a subminiature package. Choose based on the specific 4.096V output requirement. Consider the 0.2% initial accuracy tolerance for circuit precision. Evaluate the -40°C to +85°C temperature range against environmental conditions. Assess power dissipation limits relative to ambient temperatures.

Part Context

This part belongs to the LM4040 series of improved precision micropower shunt voltage references. The series offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in both SC70 and SOT23 packages with different accuracy grades ranging from 0.1% to 1%.
