8XC196KD/8XC196KD20
A to D CHARACTERISTICS
The A/D converter is ratiometric, so absolute accuracy is dependent on the accuracy and stability of VREF.

NOTES:
An ``LSB'' as used here has a value of approxiimately 5 mV. (See Embedded Microcontrollers and Processors Handbook
for A/D glossary of terms.)
1. These values are expected for most parts at 25 C but are not tested or guaranteed.
2. DC to 100 KHz.
3. Multiplexer Break-Before-Make is guaranteed.
4. Resistance from device pin, through internal MUX, to sample capacitor.
5. These values may be exceeded if the pin current is limited to g2 mA.
6. Applying voltages beyond these specifications will degrade the accuracy of other channels being converted.
7. All conversions performed with processor in IDLE mode.
