LM4041C12IDCKRG4

Overview

The LM4041C12IDCKRG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed nominal output voltage of 1.225 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum voltage temperature coefficient of 100 ppm/°C. It utilizes a SC-70-5 (SOT-353) surface-mount package. The typical operating current ranges from 45 µA to 12 mA, with a maximum supply voltage of 15 V. Output noise is typically 20 µVRMS in the 10 Hz to 10 kHz bandwidth.

Feature Summary

Provides stable reference voltage without requiring external capacitors for stability across all capacitive loads.
Offers low dynamic impedance and low output noise for high-precision applications.
Features wide operating current range suitable for battery-powered portable devices.

Applications

Data acquisition systems
Portable equipment
Battery-powered devices

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the SC-70-5 package type matches the design footprint requirements. Ensure the C-grade accuracy specification meets the circuit tolerance needs. Check for any recent Product Change Notifications regarding packaging or manufacturing site changes.

Selection Notes

Select this component when a fixed 1.225 V reference is required in a compact SC-70-5 package. It is suitable for designs needing ±0.5% initial accuracy and operation up to 85°C. Consider the 45 µA minimum current requirement for biasing circuits. Compare against other grades if tighter tolerance or wider temperature range is needed.

Part Context

This part belongs to the LM4041 family of precision micropower shunt voltage references. The family includes adjustable versions and various accuracy grades (A, B, C, D). The LM4041 series is designed for space-constrained applications, offering alternatives to larger packages while maintaining precision performance.
