This device samples an analog input voltage at regular intervals and quantizes it into a binary value that a microcontroller or DSP can process. Performance is defined by resolution in bits and sampling rate in samples per second. Common architectures include SAR, delta-sigma, and flash converters.
The analog-to-digital converter is clipping because the sensor output is exceeding the 3.3-volt reference.
