LM4040AIM3-10.0/NOPB

Overview

The LM4040AIM3-10.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10 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 150 ppm/°C. It is housed in a SOT-23-3 surface-mount package and supports a maximum shunt current of 15 mA.

Feature Summary

Provides stable fixed reference voltage for analog circuits
Micropower operation suitable for battery-powered applications
Precision tolerance ensures high accuracy in signal conditioning

Applications

Analog-to-digital converter (ADC) reference inputs
Digital-to-analog converter (DAC) voltage references
Portable instrumentation measurement systems

Procurement Notes

Verify the complete part number including suffixes such as NOPB and packaging variants like AIM3X when sourcing. Confirm RoHS compliance status and ensure the supplier provides original manufacturer documentation. Check for automotive qualification requirements if the application demands AEC-Q100 standards, as standard industrial versions differ from qualified counterparts.

Selection Notes

Select this component when a 10 V fixed reference is required in a compact SOT-23 footprint. The 1% initial accuracy and 150 ppm/°C temperature coefficient define its precision class. Ensure the design accommodates the 15 mA maximum shunt current capability and operates within the specified -40°C to +85°C ambient temperature range for reliable performance.

Part Context

This device belongs to the LM4040-N family of micropower shunt voltage references. The family offers various fixed voltage options and accuracy grades. The LM4040 series is designed to replace larger Zener diodes, providing superior stability and lower noise in space-constrained power management and signal processing designs.
