Data in ‘Typ’ column is at 5.0V, 25
°
C unless otherwise stated. These parameters are for design guidance
only and are not tested.
Note 1:
Total Absolute Error includes Integral, Differential, Offset and Gain Errors.
2:
The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.
3:
V
REF
current is from external V
REF
or V
DD
pin, whichever is selected as reference input.
4:
Only limited when V
DD
is at or below 2.5V. If V
DD
is above 2.5V, V
REF
is allowed to go as low as 1.0V.
5:
Analog input voltages are allowed up to V
DD
, however the conversion accuracy is limited to V
SS
to V
REF
.
These parameters are characterized but not tested.
