DESCRIPTION

VALUE
D7
R/W
0
0: If power down sequence is activated by device software power down using page 1 / register 46, bit
D7, then power down the DAC simultaneously with the HP and SP amplifiers.
1: If power down sequence is activated by device software power down using page 1 / register 46, bit
D7, then power down DAC only after HP and SP amplifiers are completely powered down. This is to
optimize power-down POP.
