Adafruit Precision Voltage Reference (LM4040) Breakout - 2.048V and 4.096V - Adafruit 2200
The Adafruit Precision Voltage Reference gives you 2 x high precision voltages which are accurate to 0.1%. A great little gadget for measuring the accuracy and precision of your microcontroller's analogue to digital converter (ADC) or providing a good solid reference for analogue conversion. Simply apply 5 to 12V if you want to use both references or 3V if you only need the 2.048V reference. They are only voltage references and are unable to supply any power.
Supplied as an assembled and tested board plus a strip of 0.1in. header pins for you to solder on as required.
