Qwiic 12-Bit ADC Hookup Guide
Introduction
An analog to digital converter (ADC) is very useful tool for converting an analog voltage to a digital signal that can
be read by a microcontroller. The ability to converting from analog to digital interfaces allows users to use
electronics to interface to interact with the physical world.
SparkFun Qwiic 12 Bit ADC - 4 Channel (ADS1015)
 DEV-15334
The SparkFun Qwiic (12-bit) ADC provides four channels of I C controlled ADC input to your Qwiic enabled
project. These four channels can be used as single-ended inputs, or in pairs for differential inputs. The ADS1015
uses its own internal voltage reference for measurements, but the ground and 3.3V power are also available on
the pin outs for users.
Note: The maximum resolution of the converter is 12-bits in differential mode and 11-bits for single-ended
inputs. Step sizes range from 125μV per count to 3mV per count depending on the full-scale range (FSR)
setting.
