Note 1:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the gain error and the offset
error have been nulled.
Note 2:
No missing codes over temperature.
Note 3:
Conversion time is defined as the number of clock cycles (16) multiplied by the clock period.
Note 4:
At sample rates below 10ksps, the input full-linear bandwidth is reduced to 5kHz.
Note 5:
The listed value of three SCLK cycles is given for full-speed continuous conversions. Acquisition time begins on the 14th ris-
ing edge of SCLK and terminates on the next falling edge of CNST. The IC idles in acquisition mode between conversions.
Note 6:
Undersampling at the maximum signal bandwidth requires the minimum jitter spec for SINAD performance.
Note 7:
Digital supply current is measured with the V
IH
level equal to V
L
, and the V
IL
level equal to GND.
