13.11 8-BIT ADC CHARACTERISTICS

TA = -40°C to 85°C, unless otherwise specified

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. Data based on characterization results, not tested in production.

3. 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.

4. The stabilization time of the AD converter is masked by the first tLOAD. The first conversion after the enable is then

always valid.
