Does anyone have any actual hands on experience with this concept? An explaination can be found [here I am looking at an application where I will need about 12 bits of resolution, however many microcontrollers have only 10 bits.](http://www.atmel.com/dyn/resources/prod_documents/doc8003.pdf)
is their a reason you don’t just pick one with 12bit?
Can’t find one readily available in a development board suitable for my application. I don’t really want to go the route of designing a full custom board/system.
