Or maybe your analog converter needs a good reference? Or lets say you want to test your microcontroller's conversion accuracy \u0026amp; 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!\u003c\/p\u003e\n\u003cp\u003e Using is easy, just power with about 5V-12V, or 3V if you want only the 2V reference to work. Then measure the voltage on the output. Note that these are not \u003cem\u003eregulators\u003cstrong\u003e \u003c\/strong\u003e\u003c\/em\u003e- you can't power anything off the output. They are for measurements only.
