LM4040A41IDBZRG4

Overview

The LM4040A41IDBZRG4 is a precision micropower shunt voltage reference from Texas Instruments. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.1% and a temperature coefficient of 100ppm/°C. The device operates within a free-air temperature range of -40°C to 85°C. It requires a minimum cathode current of 45μA (typical) and supports up to 15mA. Packaged in a space-saving SOT-23-3 format, it is stable with all capacitive loads without requiring an external capacitor.

Feature Summary

Offers tight output tolerance and low temperature coefficient for high precision applications
Operates stably with all capacitive loads without the need for an output capacitor
Designed for portable applications due to micropower consumption characteristics

Applications

Data-Acquisition Systems
Energy Infrastructure
Analog Input Module
Field Transmitters
Precision Audio

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's latest documentation to confirm compliance status and package details. Ensure the component grade matches the required initial accuracy and temperature coefficient specifications for the target application environment.

Selection Notes

Select this component when a fixed 4.096V reference with high precision (±0.1%) is required in a compact surface-mount package. It is suitable for designs needing stability across varying capacitive loads without additional compensation components. Consider the industrial temperature range limits when defining operating conditions.

Part Context

This part belongs to the LM4040 series of shunt voltage references, which are designed as versatile, easy-to-use references. The series utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to achieve various output voltage tolerances ranging from 0.1% to 1%. The LM4040xI variant is specifically characterized for operation over an ambient temperature range of –40°C to 85°C.
