14.12 8-BIT ADC CHARACTERISTICS
Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.
Figure 95. Typical Application with ADC
Notes:
1. Unless otherwise specified, typical data are based on TA=25°C and VDD-VSS=5V. They are given only as design guide-
lines and are not tested.
2. When VDDA and VSSA pins are not available on the pinout, the ADC refer to VDD and VSS .
3. Any added external serial resistor will downgrade the ADC accuracy (especially for resistance greater than 10k
). Data
based on characterization results, not tested in production.
4. The stabilization time of the AD converter is masked by the first tLOAD. The first conversion after the enable is then
always valid.
