TIMING CHARACTERISTICS (Figures 8 and 9)
(V DD = +4.5V to +5.5V, T A = T MIN to T MAX , unless otherwise noted.)
Note 1: Relative accuracy is the analog value’s deviation (at any code) from its theoretical value after the full-scale range is calibrated.
Note 2: V REFIN = 4.096V, offset nulled.
Note 3: On-channel grounded; sine wave applied to all off-channels.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 5: Guaranteed by design. Not subject to production testing.
Note 6: Common-mode range for the analog inputs is from AGND to V DD .
Note 7: External load should not change during the conversion for specified accuracy.
Note 8: External reference at 4.096V, full-scale input, 500kHz external clock.
Note 9: Measured as
|
V FS (4.5V) - V FS (5.5V)
|
.
Note 10: 1µF at REFOUT; internal reference settling to 0.5LSB.
