11.11 8-BIT ADC CHARACTERISTICS
Subject to general operating conditions for V
Notes:
1. Unless otherwise specified, typical data are based on T
2. The ADC refers to V
3. Any added external serial resistor will downgrade the ADC accuracy (especially for resistance greater than 10k ). Data
4. As a stabilization time for the AD converter is required, the first conversion after the enable can be wrong.
