conversions complete. However, the devices can still output data as per the timings described previously. The
devices consume dynamic power-down current (I
PD-DYNAMIC
) during data out operations. It is recommended to
stop the clock after the 32nd SCLK falling edge to further save power down to the static power-down current
level (I
PD-STATIC
). The devices power up again on the SCLK rising edge. However, they require an extra 1 µs to
power up completely. CS must be high for the 1 µs + t
ACQ
(min) period.
