INPUT SHIFT REGISTER
The input shift register is 24 bits wide. Data is loaded into the
device as a 24-bit word under the control of a serial clock input,
SCL. The input register contents for this operation is shown in
Figure 53 and Figure 54. The eight MSBs make up the command
byte. DB23 to DB20 are the command bits, C3, C2, C1, and C0,
that control the mode of operation of the device (see Table 9 for
details). The last four bits of the first byte are the address bits,
A3, A2, A1, and A0, (see Table 9 for details). The rest of the bits
are the 16-/12-bit data-word.
The AD5669R data-word comprises the 16-bit input code (see
Figure 53) while the AD5629R data word is comprised of 12-
bits followed by four don’t cares (see Figure 54).
MULTIPLE BYTE OPERATION
Multiple byte operation is supported on the AD5629R/AD5669R.
Command 1001 is reserved for multiple byte operation (see
Table 8) A 2-byte operation is useful for applications that
require fast DAC updating and do not need to change the
command byte. The S bit (DB22) in the command register
can be set to 1 for the 2-byte mode of operation. For standard
3-byte and 4-byte operation, the S bit (DB22) in the command
byte should be set to 0.
