LM4040QAIM3X2.5/NOPB

Overview

The LM4040QAIM3X2.5/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, designed for surface-mount applications in the SOT-23-3 package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 100 ppm/°C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability.

Feature Summary

AEC-Q100 qualified for automotive-grade reliability
High precision with 0.1% initial accuracy
Low temperature drift of 100 ppm/°C
Micropower operation suitable for battery-powered systems

Applications

Automotive electronic circuits requiring stable voltage references
Portable instrumentation and measurement devices
Data acquisition systems needing high accuracy
Battery-powered equipment with space constraints

Procurement Notes

Verify the complete part number including the QAI suffix and NOPB designation to ensure correct automotive grade and lead-free status. Confirm the specific revision level against the latest manufacturer datasheet. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when automotive qualification and high precision are required in a compact SOT-23-3 footprint. Compare the 100 ppm/°C temperature coefficient against application thermal requirements. Ensure the 15 mA maximum shunt current capability aligns with the circuit's power dissipation limits and load conditions during design validation.

Part Context

This part belongs to the LM4040-N series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The Q prefix indicates automotive qualification, while the AI suffix specifies the 0.1% accuracy and 100 ppm/°C performance tier within the family.

Replacement Considerations

Direct substitutes include other LM4040 variants with matching voltage and accuracy, such as LM4040AIM3-2.5/NOPB for non-automotive use. Verify package compatibility and electrical parameter alignment before substitution.
