connecting 6v to ADC?
I want to connect 6v to ADC of micro without using voltage divider, is this circuit wrong?(the rest is handled by software)
Diode is 5v6 zener:
[6v]----_|<----[ADC]
when I connect it to 5.2 volt, I get reading 2.725 volt reading(2.4v drop?) , so if I use it with 6v, and change the soft, will it work OK, I mean, will it vary a lot with temp or anything ...
