NOTES:
1. Testing is performed with V_REF = 5.12 V and F_OSC = 16 MHz.
2. An LSB, as used here, has a value of approximately 20 mV.
3. Typical values are based on a limited number of samples and are not guaranteed. Operating conditions
for typical values are room temperature and V_REF = V_CC = 5.5 V.
4. DC to 100 KHz.
5. Multiplexer break-before-make guaranteed.
6. Resistance from device pin, through internal multiplexer, to sample capacitor.
7. These values may be exceeded if the pin current is limited to ± 2mA.
8. Applying voltage beyond these specifications will degrade the accuracy of other channels being con-
verted.
9. All conversions were performed with processor in idle mode.
