Example 5: Power-Down All Channels Simultaneously while Reference is Always Powered Up
1st: Write sequence for enabling the DAC8564 internal reference all the time:

The DAC A, DAC B, DAC C, and DAC D analog outputs sequentially power-down to high-impedance upon
completion of the first and second write sequences, respectively.
Example 6: Write a Specific Value to All DACs while Reference is Always Powered Down
1st: Write sequence for disabling the DAC8564 internal reference all the time (after this sequence, the
DAC8564 requires an external reference source to function):

The DAC A, DAC B, DAC C, and DAC D analog outputs simultaneously settle to the specified values upon
completion of the fourth write sequence. (The DAC voltages update simultaneously after the 24th SCLK falling
edge of the fourth write cycle). Reference is always powered-down.
Example 7: Write a Specific Value to DAC A, while Reference is Placed in Default Mode and All Other
DACs are Powered Down to High-Impedance
1st: Write sequence for placing the DAC8564 internal reference into default mode. Alternately, this step can
be replaced by performing a power-on reset (see the Power-On Reset section):

2nd: Write sequence to power-down all DACs to high-impedance (after this sequence, the DAC8564 internal
reference powers down automatically):

3rd: Write sequence to power-up DAC A to a specified value (after this sequence, the DAC8564 internal
reference powers up automatically):

The DAC B, DAC C, and DAC D analog outputs simultaneously power-down to high-impedance, and DAC A
settles to the specified value upon completion.
