Voltage Reference datasheet and documents for LM4041DEM3-ADJ

LM4041DEM3-ADJ

Voltage Reference Overview

The LM4041DEM3-ADJ is a precision micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides an adjustable output voltage within the range of 1.24V to 20V. The device features an initial accuracy of 1% and operates with a low quiescent current of 5µA. It is housed in a compact SOT-323 (SC-70) surface-mount package. The component supports an extended industrial temperature range from -40°C to +125°C and includes a maximum temperature coefficient of 150ppm/°C.

Voltage Reference Feature Summary

Adjustable output voltage capability ranging from 1.24V to 20V via external resistors
Ultra-low operating current of 5µA suitable for battery-powered designs
High precision with 1% initial accuracy at 25°C
Stable operation with capacitive loads in space-constrained applications

Voltage Reference Applications

Portable battery-powered equipment
Data acquisition systems
Instrumentation
Process control
Precision audio components

Voltage Reference Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix 'ADJ' indicates the adjustable version rather than fixed voltage variants. Ensure the SC-70/SOT-323 package matches the design footprint requirements. Check RoHS compliance status for the specific order code.

Voltage Reference Selection Notes

Select this component when an adjustable reference voltage is required in a minimal footprint. The 5µA current draw makes it ideal for power-sensitive portable devices. Compare against fixed voltage alternatives if the application does not require variable reference levels. Ensure the load current requirements do not exceed the maximum shunt current specifications.

Voltage Reference Part Context

This part belongs to the LM4041 family of micropower shunt voltage references. The family offers both fixed and adjustable versions in small surface-mount packages. It serves as a stable reference source for analog circuits where size and power consumption are critical constraints. The technology leverages bandgap reference principles for temperature stability.
