SLAS594 – JULY 2008 ....................................................................................................................................................................................................... www.ti.com
A dummy cycle with CS low for more than 10 SCLK falling edges brings the device out of power-down mode. For
the device to reach the fully powered up condition requires 0.8 s. CS can be pulled high any time after the 10th
falling edge as shown in Figure 23. Note that the power-up time of 0.8
s is more than a single conversion cycle
at 3-MSPS speed. This means the device requires three dummy conversion frames at 3-MSPS speed or one
elongated dummy conversion frame. The data during the dummy conversion frames is invalid.
