AD7273/AD7274  
TIMING SPECIFICATIONS  
VDD = 2.35 V to 3.6 V; VREF = 2.35 to VDD; TA = TMIN to TMAX, unless otherwise noted.1 Guaranteed by characterization. All input signals  
are specified with tr = tf = 2 ns (10% to 90% of VDD) and timed from a voltage level of 1.6 V.

1 Sample tested during initial release to ensure compliance. All timing specifications given are with a 10 pF load capacitance. With a load capacitance greater than this  
value, a digital buffer or latch must be used.  
2 Mark/space ratio for the SCLK input is 40/60 to 60/40.
