Note 1:
Tested at V
DD
= 5.0V; single-ended, unipolar.
Note 2:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
Note 3:
Grounded on-channel; sine wave applied to all off channels.
Note 4:
Conversion time defined as the number of clock cycles times the clock period; clock has 50% duty cycle.
Note 5:
Guaranteed by design. Not subject to production testing.
Note 6:
The common-mode range for the analog inputs is from AGND to V
DD
.
Note 7:
Sample tested to 0.1% AQL.
Note 8:
External load should not change during conversion for specified accuracy.
Note 9:
Measured at V
SUPPLY
+ 5% and V
SUPPLY
- 5% only.
