Question about A/D Conversion

Hi,

you should not exceed VREF of the ADC! Otherwise the device will be damaged.

Hello Everyone,

I'm willing to use my uPSD chip to check li-on battery voltage. The uPSD suppose to alarm when the li-on battery voltage drops under 3.3V.

The uPSD manual claims that A/D input voltage should be less or equal to 3.6V.

In case I will connect the A/D to voltage between 4.1V and 3.6V, how it will behave? Will I receive dummy data? No data at all? Can this operation harm the device?

Thanks for help.
