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
– I2C Address: 0x48 (Default), 0x49, 0x4A, or 0x4B
• Screw pin terminals for solderless connection to voltage sources
