_______________________________________________________________________________________
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 CNVST. 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: 1.5Msps operation guaranteed for VL > 2.7V. See the Typical Operating Characteristics section for recommended sampling
speeds for VL < 2.7V.
Note 8: Digital supply current is measured with the VIH level equal to VL, and the VIL level equal to GND.
TIMING CHARACTERISTICS
(VDD = +2.7V to +3.6V, VL = VDD, VREF = 2.048V, fSCLK = 24.0MHz, 50% duty cycle, TA = -40°C to +85°C, unless otherwise noted.
Typical values are at VDD = 3V and TA = +25°C.)
