Features:

• The SparkFun Qwiic 12 Bit ADC can provide four channels of I2C controlled ADC input to your Qwiic enabled project.
• These channels can be used as single-ended inputs, or in pairs for differential inputs.

(Note: When powering with a Qwiic cable, the input range is only 3.3v)
- Operating Temperature: -40°C to 125°C
- Operation Modes: Single-Shot, Continuous-Conversion (Default), and Duty Cycling
- Analog Inputs:
- Measurement Type: Single-Ended (Default)
- Input Voltage Range: GND to VDD
- Full Scale Range (FSR): ±.256V to ±6.114V (Default: 2.048V)
- Resolution:
- 12-bit (Differential) or 11-bit (Single-Ended)
- LSB size: 0.125mV - 3mV (Default: 1 mV)
- Sample Rate: 128 Hz to 3.3 kHz (Default: 1600SPS)
- Current Consumption (Typical): 150μA-200μA
