FULL POWER-DOWN MODE
Full power-down mode is intended for use in applications
where throughput rates slower than those in partial power-
down mode are required because power-up from a full power-
down takes substantially longer than that from a partial power-
down. This mode is more suited to applications in which a
series of conversions performed at a relatively high throughput
rate are followed by a long period of inactivity and, thus, power-
down. When the AD7356 is in full power-down mode, all
analog circuitry is powered down including the on-chip
reference and reference buffers. Full power-down mode is
entered in a similar way as partial power-down mode, except
that the timing sequence shown in Figure 25 must be executed
twice. The conversion process must be interrupted in a similar
fashion by bringing CS high anywhere after the second falling
edge of SCLK and before the 10th falling edge of SCLK. The
device enters partial power-down mode at this point.
To reach full power-down, the next conversion cycle must be
interrupted in the same way, as shown in Figure 27. When CS is
brought high in this window of SCLKs, the part fully powers
down.
Note that it is not necessary to complete the 14 or 16 SCLKs
once CS has been brought high to enter a power-down mode.
To exit full power-down mode and power-up the AD7356,
perform a dummy conversion, similar to powering up from
partial power-down. On the falling edge of CS, the device begins
to power up as long as CS is held low until after the falling edge
of the 10th SCLK. The required power-up time must elapse
before a conversion can be initiated, as shown in
.
