Hi everyone,
I have some questions about MCU input protection. Although this topic has been discussed many times in this forum and others, I find myself baffled by the differing answers. Thank you in advance for your insights!
In my project, I will be using both digital input (for a motion detector) and ADC input (for temperature and photocell sensors). First, I would like to know if the protection circuits for digital input and ADC input are different.
Secondly, which of these circuits is recommended, or is there another circuit you would suggest for protecting both digital and ADC inputs?
Thanks again for your help!
