• Micropower operation suitable for battery applications
• Stable across all capacitive load conditions

Voltage Reference Applications

• Data acquisition systems
• Portable instrumentation
• Battery-powered equipment

Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB or reel/cut tape options. Confirm the specific grade (A, B, or C) if tighter tolerances are required, as the base model denotes standard accuracy. Ensure the operating environment stays within the specified industrial temperature limits.

Voltage Reference Selection Notes

Select this component when a low-cost, adjustable reference is needed in a small footprint. It is suitable for designs requiring stability without output capacitors. Consider the 12 mA maximum current limit for power dissipation calculations in high-voltage shunt configurations.

Voltage Reference Part Context

This device belongs to the LM4051 series of micropower shunt references. It serves as a compact alternative to larger packages while maintaining precision. The series supports both fixed and adjustable outputs, with this specific variant offering flexibility through external resistor networks.

Voltage Reference Replacement Considerations

LM4051AIM3-ADJ/NOPB offers higher accuracy grades. TL4051 variants provide similar functionality with different temperature ratings.
