Adafruit MCP3421 18-Bit ADC - STEMMA QT / Qwiic

The Adafruit MCP3421 18-Bit ADC offers precise, easy-to-integrate analog-to-digital conversion with its I2C interface. Functioning efficiently at a clock rate of up to 3.4MHz, it's tailored for differential input readings within the 0 to 2.048V range.Features include selectable 18-bit resolution at 3.75 SPS up to 12-bit at 240 SPS. Ideal for precision measurements like those from strain gauges or thermocouples, it seamlessly connects via STEMMA QT for solderless integration.An adjustable gain amplifier and precision low-drift voltage reference ensure accuracy. Compatibility with Arduino through a dedicated library simplifies configuration for continuous or one-shot mode readings. Combine with a multiplexor for expanded projects.
