, Gain, and Power-Down Select Bits (Note 4)
The analog output is updated when LDAC pin is (or changes to) “Low”. UDAC bit is not used for this
command.
The DAC output is updated when LDAC pin or UDAC bit is “Low”.
The device starts writing to the EEPROM on the acknowledge clock pulse of the last channel. The device
does not execute any command until RDY/BSY bit comes back to “High”.
The input and output registers are updated at the acknowledge clock pulse of the last byte. The update
does not require LDAC pin or UDAC bit conditions. EEPROM is not affected.
