1 All input signals are specified with tr = tf = 1 ns/V (10% to 90% of V
DD) and timed from a voltage level of (VIL + VIH)/2.
2 Maximum SCLK frequency is 16.667 MHz.
3 Under the load conditions that are outlined in Figure 2.
4 Time from when V
DD or VLOGIC supplies are powered-up to when a digital interface command can be executed.
5 Time required from execution of power-on software command to when the DAC output has settled to 1 V.
