NOTES:
1.
ANGND and V
SS should nominally be at the same potential.
2.
V
REF must not exceed VCC by more than + 0.5 V because VREF supplies both the resistor ladder and the
analog portion of the converter and input port pins.
3.
Program the AD_TIME register to meet the T
SAM and TCONV specifications.

Notes
NOTES:
1.
Testing is performed with V
REF = 5.12 V and FOSC = 16 MHz.
2.
An
LSB, as used here, has a value of approximately 5 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 = VCC = 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.
