LM4040DIM3-2.1-T

Overview

The LM4040DIM3-2.1-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.048 V with an initial accuracy of 1%. The device features a maximum temperature coefficient of 150 ppm/°C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +85°C and is housed in an SOT-23 package.

Feature Summary

Precision two-terminal shunt mode bandgap voltage reference
Fixed reverse breakdown voltage options for stable regulation
Micropower operation suitable for power-restricted designs
Compact surface-mount packaging for space-critical applications

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring stable reference voltages
Space-constrained electronic circuits
Industrial control systems operating in wide temperature ranges

Procurement Notes

Verify the exact suffix against official manufacturer documentation, as variations such as '+T' or '/NOPB' may indicate specific tape-and-reel configurations or lead-free compliance. Confirm availability status directly with authorized distributors, as supply constraints can affect delivery timelines. Ensure the selected variant matches the required accuracy and temperature grade for your specific application design.

Selection Notes

Select this component when a 2.048 V reference with 1% initial accuracy is sufficient for the circuit requirements. Consider the 150 ppm/°C temperature coefficient for thermal stability needs. The SOT-23 package is ideal for designs prioritizing minimal board space. Compare against higher accuracy variants like the LM4040B series if tighter tolerance is required.

Part Context

The LM4040 series comprises low-power, high-accuracy shunt voltage references available in multiple fixed output voltages including 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. The family offers various accuracy grades (A, B, C, D) and packages (SOT-23, SC-70), designed for industrial temperature ranges up to 125°C in some variants, providing stable performance across diverse application conditions.
