LM4040CIX3-2.1+

Overview

The LM4040CIX3-2.1+ is a micropower shunt voltage reference manufactured by Analog Devices / Maxim Integrated. It provides a nominal output voltage of 2.048 V with an initial accuracy of 1%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA. It is housed in a compact SC-70 (SOT-323) surface-mount package, designed for space-constrained applications requiring stable voltage regulation.

Feature Summary

Provides a fixed 2.048 V precision reference output
Operates as a two-terminal shunt regulator
Utilizes ultra-small SC-70 surface-mount packaging

Applications

Portable battery-powered instrumentation
Handheld measurement devices
Data acquisition systems

Procurement Notes

Verify the manufacturer designation on the component marking, as this part number may be sourced from Analog Devices or Texas Instruments depending on the specific production lot. Confirm the suffix indicates the standard 1% accuracy grade and SC-70 package variant. Ensure compatibility with existing PCB footprints for the SOT-323 form factor before integration.

Selection Notes

Select this component when a low-cost, small-footprint voltage reference is required for non-critical precision applications. The 1% initial accuracy and 100 ppm/C temperature coefficient are suitable for general-purpose analog circuits. Consider higher accuracy grades if tighter tolerance specifications are necessary for the target design.

Part Context

This component belongs to the LM4040 family of micropower shunt voltage references. The series offers various fixed output voltages and accuracy grades to support diverse power management needs. The LM4040CIX3-2.1+ specifically addresses the need for a compact, cost-effective reference solution in consumer electronics and industrial control modules.
