Multislope ADC: A self-made high-resolution multislope ADC based on a Raspberry Pi Pico (Understanding ADCs)

 
Overview
Built using operational amplifiers, logic chips, and a Raspberry Pi Pico. This type of ADC measures analog values ​​by calculating the time required to charge a capacitor to a given voltage. A simpler version measuring charging time has some drawbacks, so this project compares charging and discharging times to voltage, from single-slope to multi-slope measurements. With careful component matching and reference stability, this design can provide very high-resolution measurements.
