The device is functional over a wider range which is specified under Operating Ratings. ADC102S021 Timing Specifications The following specifications apply for VA = +2.7V to 5.25V, GND = 0V, CL = 50 pF, fSCLK = 0.8 MHz to 3.2 MHz, fSAMPLE = 50 ksps to 200 ksps, Boldface limits apply for TA = TMIN to TMAX: all other limits TA = 25°C. Parameter Test Conditions Typ Limits(1) Units VA = +3.0V −3.5 tCSU Setup Time SCLK High to CS Falling Edge See(2) 10 ns (min) VA = +5.0V −0.5 VA = +3.0V +4.5 tCLH Hold time SCLK Low to CS Falling Edge See(2) 10 ns (min) VA = +5.0V +1.5 (1) Tested limits are specified to Texas Instrument's AOQL (Average Outgoing Quality Level). (2) Clock may be either high or low when CS is asserted as long as setup and hold times tCSU and tCLH are strictly observed.
