LM4041BIM3X-1.2/NOPB

Overview

The LM4041BIM3X-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 1.225 V. It utilizes an SOT-23-3 surface-mount package and operates within an industrial temperature range of -40°C to +85°C. The device offers an initial accuracy of ±0.2% and a maximum temperature coefficient of 100 ppm/°C. Typical minimum operating current is 45 µA, with a maximum cathode current of 12 mA. It exhibits low dynamic impedance and noise (20 µVRMS typical), ensuring stability across wide current and temperature variations without requiring external stabilizing capacitors.

Feature Summary

Provides high-precision fixed voltage reference with tight initial tolerance and low temperature drift
Operates stably with any capacitive load without the need for external stabilization capacitors
Designed for space-constrained applications using sub-miniature surface-mount packaging

Applications

Data acquisition systems
Power supply monitoring circuits
Instrumentation and test equipment

Procurement Notes

Verify the specific suffix 'B' indicates the B-grade accuracy tier (±0.2%) and 'M3' denotes the SOT-23-3 package configuration. Confirm the 'NOPB' suffix aligns with RoHS compliance requirements. Ensure the operating environment remains within the specified industrial temperature range of -40°C to +85°C to maintain rated performance specifications.

Selection Notes

Select this component when a fixed 1.225 V reference with higher precision than standard grades is required in a compact footprint. It is suitable for designs needing stable performance across varying loads without external compensation components. Consider the 45 µA minimum current requirement for battery-powered applications where quiescent power consumption is critical.

Part Context

This part belongs to the LM4041-N family of precision micropower shunt voltage references from Texas Instruments. The family includes adjustable versions and various accuracy grades (A, B, C, D) packaged in SC-70, SOT-23, and TO-92 formats. The LM4041 series is engineered for applications demanding low noise, low dynamic impedance, and high stability over wide operating conditions.
