MAX10 ADC DC characteristics

Hello, what is the maximum non-destructive voltage level, which can be tolerated for limited period of time by MAX10 ADC input channel, provided VCCA and VCCIO1A are 3.3V for single supply device?...

Hi Frank,


According to datasheet, as you mentioned, the analog input voltage can go up to Vref, while Vref can go up to VCC_ONE as the maximum value.


Since your VCC_ONE is 3.3V, the maximum analog input voltage would be 3.3V. It is similar with the statement you found in the ADC user guide.


Regards,

Aqid

Hello Aqid,

In order to exclude any misconceptions: Let me rephrase my question.

With respect to below voltage conditions, would an ADC input voltage of up to 3.3V (Vadc_in > Vref & Vadc_in <= VCC_ONE) cause any damage or impact device reliability or life time?

Vref = 3.0V
VCC_ONE = 3.3V
VCCAx = 3.3V
VCCIO1A = 3.3V

Best regards
Frank
