Or lets say you want to test your microcontroller's conversion accuracy &amp; 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 the 2V reference to work. Then measure the voltage on the output. Note that these are not regulators&nbsp;- you can't power anything off the output. They are for measurements only. For more details, check the LM4040 Datasheet for more information.","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9109,"title":"Default Title","sku":"AF-2200","price":15.12,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
