Frequently Asked Questions
What is the accuracy of the LM4040CIM3-3.0/NOPB voltage reference?
The LM4040CIM3-3.0/NOPB provides 1% initial accuracy at 25°C with a nominal reference voltage of 3.000V. The C-grade offers the best balance of accuracy and cost for general-purpose measurement and ADC reference applications.
What is the operating current range of the LM4040CIM3-3.0/NOPB?
The device operates from a minimum of 60µA to a maximum of 15mA shunt current, making it one of the lowest power voltage references available. This micropower capability enables use in battery-powered and energy-harvesting applications.
How does the LM4040 shunt reference work?
The LM4040 operates as a precision shunt regulator, similar to a Zener diode but with far better accuracy and temperature stability. It is connected in reverse bias with a series resistor from the supply, maintaining a precise 3.0V across its terminals.
What package is the LM4040CIM3-3.0/NOPB available in?
The device comes in a 3-pin SOT-23 package measuring 2.9mm x 1.3mm, the industry-standard small outline transistor package. This tiny footprint is ideal for space-constrained portable instruments and sensor modules.
What are common applications for the LM4040CIM3-3.0/NOPB?
Typical applications include ADC voltage reference for 3V systems, battery level monitoring in portable devices, threshold detection circuits, and precision biasing in sensor interfaces. It replaces Zener diodes where better accuracy is needed.
