SparkFun Blocks for Intel® Edison - ADC V20
Introduction
NOTE: This tutorial applies to V20 and V21 of the ADC Block. V21 corrects the voltage noise and adds a locking header footprint for easier assembly with the Edison SIK.
SparkFun’s ADC Block for the Intel Edison allows you to add four channels of I2C controlled ADC input to your Edison stack. These four channels can be used as single-ended inputs, or in pairs as differential inputs. A ground reference is provided for each channel.
The maximum resolution of the converters is 12 bits, or 11 bits bipolar in differential mode. Step sizes range from 125uV per count to 3mV per count.
