How good is your multimeter really? Or maybe your analog converter
needs a good reference? Or lets say you want to test your
microcontroller's conversion accuracy & precision. If only you had a
dependable, high precision, rock-solid voltage reference. Now you know
why we made this very cute and useful little breakout board. It has
two very high precision shunt-type voltage references with 750 ohm
biasing resistors. One is 2.048V (great for 3.3V reference systems)
and the other is 4.096 (great for 5V). Both are 0.1% accuracy!

Using is easy, just power with about 5V-12V, or 3V if you want only

that these are not regulators - you can't power anything off the
