LM4041QAIM3-1.2/NO

Voltage Reference Overview

The LM4041QAIM3-1.2/NO is a precision micropower shunt voltage reference from Texas Instruments, providing a fixed output of 1.225 V. It features an initial accuracy of ±0.1% and a maximum temperature coefficient of 100 ppm/°C. The device operates within a wide current range of 45 μA to 12 mA and maintains stability with all capacitive loads without requiring external compensation components. Designed for extended industrial applications, it supports an operating temperature range from -40°C to +125°C. The component is AEC-Q100 qualified and housed in a compact SOT-23-3 surface-mount package.

Voltage Reference Feature Summary

AEC-Q100 qualified for automotive reliability standards
Ultra-low operating current suitable for battery-powered systems
Inherently stable with any capacitive load configuration

Voltage Reference Applications

Automotive electronic control units

Battery-operated data acquisition systems

Voltage Reference Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 qualification status and 'I' indicates the extended temperature range capability. Ensure the '/NO' designation aligns with RoHS compliance requirements for your manufacturing process. Confirm that the SOT-23-3 footprint matches your PCB layout constraints before finalizing procurement orders.

Voltage Reference Selection Notes

Select this part when high precision at low currents is required in space-constrained designs. The 1.225V output is ideal for ADC references or comparator thresholds. Consider the ±0.1% tolerance if tight voltage regulation is critical. Evaluate the 100 ppm/°C drift against thermal environment variations to ensure long-term system accuracy meets specifications.

Voltage Reference Part Context

This component belongs to the LM4041 family of micropower shunt references. It complements other variants like the LM4041CIM3X-1.2/NOPB by offering enhanced automotive-grade durability and extended temperature performance. The series provides scalable options ranging from 0.1% to 1% accuracy grades, allowing designers to balance cost and precision effectively across different product tiers.
