Load DAC registers A and B from respective input registers; DAC
outputs A and B updated; MAX5513/MAX5515 enter normal
operation if in standby or shutdown; MAX5512/MAX5514 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; MAX5513/MAX5515 enter normal operation if in
standby or shutdown; MAX5512/MAX5514 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; MAX5513/MAX5515 enter normal operation if in
standby or shutdown; MAX5512/MAX5514 enter normal operation
if in shutdown.
Command reserved. Do not use.
MAX5513/MAX5515 enter standby*, MAX5512/MAX5514 enter
shutdown. For the MAX5513/MAX5515, D7 and D6 configure the
internal reference voltage (Table 3).
MAX5512–MAX5515 enter normal operation; DAC outputs reflect
existing contents of DAC registers. For the MAX5513/MAX5515,
D7 and D6 configure the internal reference voltage (Table 3).
MAX5512–MAX5515 enter shutdown; DAC outputs set to high
impedance. For the MAX5513/MAX5515, D7 and D6 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; MAX5513/MAX5515 enter
normal operation if in standby or shutdown; MAX5512/MAX5514
enter normal operation if in shutdown.
No operation; command is ignored.
