Qwiic 24 Bit ADC - 4 Channel (ADS1219)
Product description
The SparkFun Qwiic 24-Bit ADC (ADS1219) adds four channels of high-precision, 24-bit analog input to your project over I2C, featuring programmable gain and up to 16 unique addresses.
Sometimes, the standard 10-bit or 12-bit ADC built into your microcontroller just isn't enough. When you need to measure minute changes in voltage with extreme accuracy, the SparkFun Qwiic 24-Bit ADC is the tool for the job. Built around the Texas Instruments ADS1219, this board provides four channels of high-resolution analog input, configurable as four single-ended inputs or two differential pairs.
To help you measure even the smallest signals (like those from strain gauges or scientific sensors), the chip features a programmable gain amplifier (PGA) with x1 and x4 gain settings. This allows you to "zoom in" on tiny voltage fluctuations with incredible precision, down to 61.04 nV per count.
