LM4040QDIM3-2.5/NOPB

Overview

The LM4040QDIM3-2.5/NOPB is an automotive-grade precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 1%. The device features a 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 +125°C and is housed in a compact SOT-23-3 surface-mount package. The component holds AEC-Q100 qualification for automotive applications.

Feature Summary

AEC-Q100 qualified for automotive reliability standards
Precision micropower shunt voltage reference design
Extended high-temperature operation up to 125°C

Applications

Automotive electronic systems requiring stable voltage references
High-precision data acquisition circuits
Analog-to-digital converter (ADC) reference sources

Procurement Notes

Verify the specific suffix 'QDI' confirms AEC-Q100 automotive qualification and the '-2.5' indicates the 2.5V output variant. Confirm the '/NOPB' designation ensures lead-free and RoHS compliance as per manufacturer specifications. Cross-reference the full part number against official Texas Instruments documentation to ensure correct package type and electrical parameters.

Selection Notes

Select this component when automotive qualification and extended temperature range are required. The 1% accuracy and 150 ppm/°C temperature coefficient suit general precision applications. Ensure the circuit design accommodates the 15 mA maximum shunt current limit and the SOT-23-3 package constraints for thermal and space requirements.

Part Context

This part belongs to the LM4040-N series, which offers various fixed voltage options and accuracy grades. The QDI suffix specifically denotes the automotive grade version with enhanced reliability testing compared to standard industrial variants like CIM3 or EIM3. It serves as a compact solution for replacing larger through-hole references in modern surface-mount designs.
