LM4041CIM7X-1.2/NOPB

Overview

The LM4041CIM7X-1.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 1.225 V. It operates within an extended temperature range of -40°C to +125°C and utilizes the SC-70 (SOT-323) surface-mount package. The device offers an initial accuracy of ±0.5% at 25°C with a maximum temperature coefficient of 100 ppm/°C. It functions without external stabilizing capacitors across all capacitive loads, drawing a minimum operating current of 60 µA and supporting a maximum cathode current of 12 mA.

Feature Summary

Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
Provides high precision through fuse and Zener-zap reverse breakdown voltage trim during wafer sort
Features bandgap reference temperature drift curvature correction for stable performance over wide temperature ranges
Designed for space-critical applications using sub-miniature surface-mount packaging

Applications

Data acquisition systems requiring precise voltage references
Portable battery-powered equipment due to low power consumption
Handheld instruments and measurement devices
Temperature compensated circuits and monitoring systems

Procurement Notes

Verify the specific suffix 'CIM7X' corresponds to the industrial temperature grade (-40°C to +85°C or +125°C depending on exact TI revision) and SC-70 package configuration. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance as per Texas Instruments standards. Ensure the ordering part number matches the required tolerance grade and output voltage specification before procurement.

Selection Notes

Select this component when a compact form factor is required alongside high precision in portable designs. The fixed 1.225 V output suits applications needing a stable reference without external resistor dividers. Consider the ±0.5% accuracy and 100 ppm/°C drift for environments demanding thermal stability. Verify that the 60 µA minimum current meets the system's quiescent power constraints.

Part Context

This device belongs to the LM4041-N family of precision micropower shunt voltage references from Texas Instruments. The family includes adjustable versions and various tolerance grades (A, B, C, D). The CIM7X variant specifically denotes the industrial temperature range and SC-70 package, distinguishing it from automotive or higher-grade counterparts within the same functional series.
