### AI overview

This article compares ADC specifications, accuracy, and calibration approaches across Espressif SoCs. It explains ESP-IDF line-fitting and curve-fitting calibration schemes and discusses how calibration can improve ADC readings, while noting that custom schemes may not work consistently across chips in mass production.

### Source excerpt

This article compares the Analog-to-Digital Converter (ADC) performance of different Espressif SoCs and shows the techniques to improve the ADC accuracy using software calibration. The results should help developers choose the most suitable SoC and optimize it for their application's accuracy and voltage range requirements.
