LM4040DEX3-4.1

Overview

The LM4040DEX3-4.1 is a micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096 V with an initial accuracy of 1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 200 PPM/°C. It supports a maximum shunt current of 15 mA and consumes a cathode current of 73 µA. The component is housed in an SC-70-3 surface-mount package, suitable for space-constrained applications requiring stable voltage regulation.

Feature Summary

Provides a precise fixed output voltage of 4.096 V for circuit regulation.
Operates with low power consumption, drawing only 73 µA of cathode current.
Designed for high stability across industrial temperature ranges from -40°C to +85°C.

Applications

Portable battery-powered instrumentation
Handheld meters
Data acquisition systems

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated when sourcing this component. Confirm the specific suffix 'D' corresponds to the required 1% accuracy and 200 PPM/°C temperature coefficient specifications. Ensure the SC-70-3 package type matches your PCB footprint requirements before procurement.

Selection Notes

Select this part when a compact, low-power shunt reference is needed for 4.096 V applications. It is suitable for designs where moderate precision (1%) and standard temperature stability are sufficient. Consider the SC-70-3 package size for tight board layouts. Compare against higher accuracy variants if tighter tolerance or lower temperature drift is required for the specific application.

Part Context

This component belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The 'DEX3' designation indicates the specific pinout, package style, and performance grade associated with Maxim Integrated's implementation of this reference topology.
