12.13 10-BIT ADC CHARACTERISTICS

Subject to general operating conditions for VDD, fCPU, and TA unless otherwise specified.

Notes:

1. Any added external serial resistor will downgrade the ADC accuracy (especially for resistance greater than 10k

Ω). Data

based on characterization results, not tested in production.
