LM4041BIM3-1.2

Overview

The LM4041BIM3-1.2 is a micropower shunt voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 1.225 V with an initial accuracy of 0.2% at 25 °C. The device operates within a temperature range of -40 °C to +85 °C and features a maximum temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 12 mA and is housed in a SOT-23-3 surface-mount package.

Feature Summary

Provides stable reverse breakdown voltage with bandgap reference temperature drift curvature correction
Operates without requiring an external stabilizing capacitor
Maintains stability when connected to capacitive loads

Applications

Space-critical applications utilizing sub-miniature packages
Power restricted designs requiring low operating current
Precision measurement systems needing stable reference voltages

Procurement Notes

Verify the manufacturer designation, as this component is listed under both Texas Instruments and Analog Devices/Maxim Integrated due to corporate acquisition history. Confirm the specific suffix matches the required tolerance and temperature grade. Ensure the ordering information aligns with the current datasheet specifications for the LM4041-B variant to avoid discrepancies in electrical parameters or package details.

Selection Notes

Select this component for applications demanding high precision in a small footprint. The 0.2% initial accuracy and low temperature coefficient make it suitable for sensitive analog circuits. Consider the 12 mA maximum current limit when designing bias networks. Verify compatibility with the system's operating temperature range, as this specific part is rated for industrial temperatures.

Part Context

The LM4041 series belongs to a family of precision micropower shunt voltage references designed for space-constrained environments. These devices utilize advanced zener-zap trimming during wafer sort to achieve tight initial accuracy. The series includes both fixed and adjustable versions, offering flexibility for various reference voltage requirements in portable and battery-powered electronics.
