ANGND and V
should nominally be at the same potential.
V
must not exceed V
by more than + 0.5 V because V
REF
supplies both the resistor ladder and the
analog portion of the converter and input port pins.
Program the AD_TIME register to meet the T
SAM
and T
CONV
specifications.

Testing is performed with V
= 5.12 V and F
= 16 MHz.
An LSB as used here, has a value of approximately 5 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
= V
CC
= 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.
