A to D Converter Specifications
The speed of the A/D converter in the 10-bit or 8-bit modes can be adjusted by setting the
AD_TIME special function register to the appropriate value. The AD_TIME register only
programs the speed at which the conversions are performed, not the speed at which it can convert
correctly.
The converter is ratiometric, so absolute accuracy is dependent on the accuracy and stability of

digital portion of the converter and input port pins.
For testing purposes, after a conversion is started, the device is placed in the IDLE mode until the
conversion is complete. Testing is performed at V
There is an AD_TEST register that allows for conversion on ANGND and V
offset adjustment. The absolute error listed is without doing any adjustments.
NOTES:
1. ANGND and V
2. V
3. Testing is performed at V
4. The value of AD_TIME must be selected to meet these specifications.
