Load DAC registers A and B from respective input registers; DAC
outputs A and B updated; MAX5523/MAX5525 enter normal
operation if in standby or shutdown; MAX5522/MAX5524 enter
normal operation if in shutdown.
Load input register A and DAC register A from shift register; DAC
output A updated; Load DAC register B from input register B; DAC
output B updated; MAX5523/MAX5525 enter normal operation if in
standby or shutdown; MAX5522/MAX5524 enter normal operation
if in shutdown.
Load input register B and DAC register B from shift register; DAC
output B updated; Load DAC register A from input register A; DAC
output A updated; MAX5523/MAX5525 enter normal operation if in
standby or shutdown; MAX5522/MAX5524 enter normal operation
if in shutdown.
Command reserved. Do not use.
MAX5523/MAX5525 enter standby*, MAX5522/MAX5524 enter
shutdown. For the MAX5523/MAX5525, D9 and D8 configure the
internal reference voltage (Table 3).
MAX5522–MAX5525 enter normal operation; DAC outputs reflect
existing contents of DAC registers. For the MAX5523/MAX5525,
D9 and D8 configure the internal reference voltage (Table 3).
MAX5522–MAX5525 enter shutdown; DAC outputs set to high
impedance. For the MAX5523/MAX5525, D9 and D8 configure the
internal reference voltage (Table 3).
Load input registers A and B and DAC registers A and B from shift
register; DAC outputs A and B updated; MAX5523/MAX5525 enter
normal operation if in standby or shutdown; MAX5522/MAX5524
enter normal operation if in shutdown.
