LM4041CEM3-ADJ

Overview

The LM4041CEM3-ADJ is a precision micropower shunt voltage reference manufactured by Texas Instruments. It operates within an industrial temperature range of -40°C to +85°C and utilizes a SOT-23-3 surface-mount package. The device features adjustable output voltage capability, allowing settings between 1.225V and 10V using external resistors. It offers a maximum initial accuracy of ±0.5% and a typical temperature coefficient of 100 ppm/°C. The component supports a wide operating current range from 45µA to 12mA and maintains stability with any capacitive load without requiring external output capacitors.

Feature Summary

Adjustable output voltage configuration via external resistor divider
Stable operation with all capacitive loads without external compensation
Low dynamic impedance and low noise characteristics for precision applications

Applications

Data acquisition systems
Portable battery-powered equipment
Precision audio circuits
Process control instrumentation

Procurement Notes

Verify the specific suffix 'CEM3' corresponds to the SOT-23-3 tape-and-reel packaging format. Confirm the 'ADJ' designation indicates the adjustable variant rather than a fixed voltage option. Ensure the C-grade tolerance meets the design requirements for the target application environment.

Selection Notes

Select this component when adjustable reference voltages are required in space-constrained designs. The SOT-23-3 package provides a compact footprint suitable for portable devices. Verify that the system can accommodate the minimum operating current of 45µA to ensure proper regulation and stability under light load conditions.

Part Context

This part belongs to the LM4041 family of precision shunt references. The series includes fixed and adjustable variants across multiple accuracy grades (A through D) and temperature ranges. The LM4041 is designed as a drop-in replacement for older Zener diodes, offering superior temperature stability and lower noise performance in analog signal conditioning paths.
