Product description
Adafruit ADS122C04 is a 24-bit A/D converter module with four analog inputs and an I²C interface. The inputs can be used as four single-ended or two differential inputs. The sampling rate is programmable up to 2 kSPS, and the built-in amplifier can be set to a gain between 1 and 128.
The module features an internal 2.048 V reference voltage and temperature sensor, as well as connections for external positive and negative reference voltages. Two solder jumpers for address selection allow up to four modules to be connected to the same I²C bus. The board is equipped with two Qwiic connectors.
