Product details

How accurate is your multimeter really? Or perhaps your analog converter needs a good reference? Or let's say you want to check the conversion accuracy and precision of your microcontroller. If you just need a reliable, high-precision, rock-solid voltage reference, you now know why we developed this very cute and useful little board. It features two very high-precision shunt voltage references with 750 Ohm bias resistors. One of them is 2.048 V (ideal for 3.3 V reference systems) and the other is 4.096 V (great for 5 V). Both have an accuracy of 0.1%!

Using it is simple: connect the power supply with about 5 V to 12 V, or 3 V if you only want to use the 2 V reference. Then measure the voltage at the output. Please note that these are not regulators - you cannot draw anything from the output.
