About this product


Product overview

• Use this breakout to test that your multimeter is accurate
• Great reference for analogue to digital converters
• Simple but effective
• Requires some light soldering

What is the LM4040 Breakout Board?
The LM4040 Breakout Board is designed for testing purposes as it always outputs a specific voltage. Use the LM4040 Breakout to make sure your multimeter is giving a correct reading. You can utilise this breakout board to test that your microcontroller’s conversion is accurate and precise. A great way to use this is for testing analogue to digital convertors as you will be generating 1 bit per millivolt.

A breakout board allows you to easily integrate awkward groups of parts into your projects

How to get the most out of your project
If you’re looking to use the 4.096 reference you will need to power this breakout board with a minimum of 5 V, to use the 2.048 you can use as little as 3 V.
You cannot use this breakout board to power components and is only for reference and testing purposes.

The header pins allow for quick and easy attachment to a breadboard allowing for all your prototyping and testing needs without messy wires. The header pins do not come attached, enabling you to attach wires instead; this is great for more permanent application.
