Notes to the characteristics
1.
V

should be supplied from the same power supply and decoupled separately.
2.
The analog supply current is directly proportional to the series resistance between V
DDA
and CLREF.
3.
CREFH and CREFL are connected respectively to the top and bottom reference ladders of the 3 analog-to-digital
converters.

The analog input settling time is the minimum time required for the input signal to be stabilized after a sharp full-scale
input (square-wave signal) in order to sample the signal and obtain correct output data.
Output data acquisition: output data is available after the maximum delay time of t
