NOTES:

Testing is performed with V

REF = 5.12 V and FOSC = 16 MHz.

LSB, as used here, has a value of approximately 20 mV.

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 = VCC = 5.5 V.

DC to 100 KHz.

Multiplexer break-before-make guaranteed.

Resistance from device pin, through internal multiplexer, to sample capacitor.

These values may be exceeded if the pin current is limited to ± 2mA.

Applying voltage beyond these specifications will degrade the accuracy of other channels being con-

verted.

All conversions were performed with processor in idle mode.
