(1)

All input signals are specified with tr = tf = 5 ns (10% to 90% of VDD) and timed from a voltage level of (VIL + VIH)/2.

(2)

See timing diagram in Figure 1.

(3)

Min tC(SCLK) is determined by the Min tSAMPLE of the specific resolution and supply voltage. See Acquisition Time, Conversion Time, and

Total Cycle Time section for further details.
