SparkFun Qwiic 24 Bit ADC - 4 Channel (ADS1219)

The SparkFun Qwiic 24-Bit ADC is a high-resolution analog-to-digital converter designed for precision voltage measurements. Built around the Texas Instruments ADS1219, it offers four channels configurable as either single-ended inputs or differential pairs. The integrated programmable gain amplifier allows for gain settings of x1 and x4, enabling precise measurements down to 61.04 nanovolts per count.

This ADC is ideal for applications requiring high accuracy, such as monitoring strain gauges or scientific sensors. Its ability to detect minute voltage changes makes it perfect for projects where precision is paramount. Whether you're working on a research project or developing a product prototype, this ADC ensures you capture even the smallest signals with clarity.

One of its standout features is the Qwiic Connect System, which facilitates easy integration with microcontrollers without the need for soldering. Simply plug it in, and you're ready to go. If your project demands more inputs, the board supports daisy-chaining up to 16 units, providing a total of 64 channels on a single bus. This scalability makes it a versatile choice for complex setups.

For those who prefer traditional methods, the board includes breakout pads spaced at 2.54mm for analog inputs, interrupts, and reference pins, allowing for flexible connections and external reference voltage inputs. Whether you're a hobbyist or a professional, this ADC offers the adaptability and precision needed for advanced electronic projects.
