• The potential for failures is highest at low V
After extended stress the Most Significant bit
(MSb) of the ADC conversion result can become
stuck at ‘0’. Conversions resulting in code 511 or
less are still accurate, but conversions that
should result in codes greater than 511 are
instead pinned at 511.
The potential for failures is a function of several
factors:
