, unless otherwise noted.)
Note 1:
Tested at V
DD
= +2.7V.
Note 2:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range and
offset have been calibrated.
Note 3:
Offset nulled.
Note 4:
Sample tested to 0.1% AQL.
Note 5:
External load should not change during conversion for specified accuracy.
Note 6:
Guaranteed by design. Not subject to production testing.
Note 7:
Measured as [V
FS
(V
DD(min)
) - V
FS
(V
DD(max)
)].
Note 8:
To guarantee acquisition time, t
ACQ
is the maximum time the device takes to acquire the signal, and is also the minimum
time needed for the signal to be acquired.
