AD5346/AD5347/AD5348
The bias generator, the output amplifier, the resistor string, and
all other associated linear circuitry are all shut down when the
power-down mode is activated. However, the contents of the
registers are unaffected when in power-down. The time to exit
power-down is typically 2.5 s for V
DD
= 5 V and 5 μs when V
DD
=
3 V. This is the time from a rising edge on the PD pin to when
the output voltage deviates from its power-down voltage. See
Figure 31.

SUGGESTED DATA BUS FORMATS
In many applications, the GAIN and BUF pins are hardwired.
However, if more flexibility is required, they can be included in
a data bus. This enables the user to software program GAIN,
giving the option of doubling the resolution in the lower half of
the DAC range. In a bused system, GAIN and BUF may be
treated as data inputs because they are written to the device
during a write operation and take effect when LDAC is taken
low. This means that the reference buffers and the output
amplifier gain of multiple DAC devices can be controlled using
common GAIN and BUF lines. Note that GAIN and BUF are
not read back during an RD operation.

The AD5347 and AD5348 data bus must be at least 10 and 12
bits wide, respectively, and are best suited to a 16-bit data bus
system.
Examples of data formats for putting GAIN and BUF on a
16-bit data bus are shown in Figure 40. Note that any unused
bits above the actual DAC data may be used for GAIN and BUF.
