Symbol
T
Testing is performed with V
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
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.
