My question is about the principle of SAR(Successive Approximation Register)ADC process in STM32 platform. The document is in the following attachment.
You can also download it from ST official site (Download this file (AN2834) from ST).
Questions as follow.
[*] 1. Do the Capacitors discharge after the HOLD STATE?
[*] 2. Have the Capacitors been fully charged?
[*] 3. Why VCOMP=-VIN+VREF/2? How to get that equation?
