Select Bits Programming Example:
To load DAC register B from input register B while
keeping channel A unchanged, set MB = 1 and MA =
0, as in the command in Table 7.
Shutdown-Mode Bits (PDA0, PDA1, PDB0, PDB1)
Use the shutdown-mode bits to shut down each DAC
independently. Set PD_0 and PD_1 according to Table
8 to select the shutdown mode for DAC_, where
“
_
”
is
replaced with A or B depending on the selected chan-
nel. The three possible states for unity-gain versions
are 1) normal operation, 2) shutdown with 1k
output
impedance, and 3) shutdown with 100k
output imped-
ance. The three possible states for force-sense ver-
sions are 1) normal operation, 2) shutdown with 1k
output impedance, and 3) shutdown with high-imped-
ance output. Table 9 shows the command for writing to
the shutdown mode bits.
Shutdown-Mode Bits Write Example:
To put a unity-gain version
’
s DACA into shutdown
mode with internal 1k
termination to ground and
DACB into the shutdown mode with the internal 100k
termination to ground, use the command in Table 10
(applicable to unity-gain output only).
To read back the shutdown-mode bits, use the com-
mand in Table 11.
