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. https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2025-11-11 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2025-12-04 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2025-12-20 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-01-24 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-01-29 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-02-01 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-03-15 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-03-20 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-04-08 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-06-12 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-06-16 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-06-19 https://elecena.pl/product/29497796/adafruit-mcp3421-18-bit-adc-stemma-qt-qwiic 2026-07-01
