LM4041QDIM3-ADJ/NO

Voltage Reference Overview

The LM4041QDIM3-ADJ/NO is a precision micropower shunt voltage reference from Texas Instruments, designed for high-accuracy applications requiring stable reverse breakdown voltages. It features an adjustable output range of 1.225 V to 10 V and is housed in a compact SOT-23 (SC-70) surface-mount package. The device operates with a minimum current of 60 µA and supports a maximum operating current of 12 mA. It maintains stability across all capacitive loads without external components and offers initial accuracy better than ±0.1% at 25°C. The unit functions within an extended temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
• Utilizes fuse and Zener-zap reverse breakdown or reference voltage trim during wafer sort for high accuracy
• Incorporates bandgap reference temperature drift curvature correction for stable performance over wide temperature ranges

Voltage Reference Applications

• Data acquisition systems
• Power and power supply monitoring
• Instrumentation and test equipment
• Process control systems
• Precision audio applications

Voltage Reference Procurement Notes

Verify that the specific suffix 'Q' confirms AEC-Q100 automotive qualification status as per official documentation. Ensure the 'ADJ' designation matches the required adjustable voltage configuration between 1.225 V and 10 V. Confirm the 'NOPB' indicates lead-free compliance and the 'DIM3X' corresponds to the correct SOT-23/SC-70 package variant. Cross-reference the manufacturer part number against the latest datasheet revision to ensure functional equivalence.

Voltage Reference Selection Notes

Select this component when space-constrained designs require a precision shunt reference with automotive-grade reliability. The adjustable output allows flexibility in setting reference levels compared to fixed versions. Consider the low dynamic impedance and low noise characteristics for sensitive analog signal paths. Verify that the operating current requirements align with the 60 µA minimum and 12 mA maximum limits specified for the Q-grade variant.

Voltage Reference Part Context

This part belongs to the LM4041-N family of precision voltage references, which includes both fixed and adjustable options. The LM4041 series is characterized by its sub-miniature packaging options, including SC-70 and SOT-23, making it suitable for portable and space-critical applications.
