OPERATING EXAMPLES: DAC8564
For the following examples, ensure that DAC pins A0 and A1 are both connected to ground. Pins A0 and A1
must always match data bits DB22 and DB23 within the SPI write sequence/protocol. X = don't care. Value can
be either '0' or '1'.
Example 1: Write to Data Buffer A Through Buffer D; Load DAC A Through DAC D Simultaneously

The DAC A, DAC B, DAC C, and DAC D analog outputs simultaneously settle to the specified values upon
completion of the 4th write sequence. (The DAC voltages update simultaneously after the 24th SCLK falling edge
of the fourth write cycle).
Example 2: Load New Data to DAC A Through DAC D Sequentially
•
1st: Write to data buffer A and load DAC A: DAC A output settles to specified value upon completion:
