DESCRIPTION

VALUE
After power-on or reset, all bits in the Power-Down Register are
0
cleared to '0', and all the components controlled by this register
are either powered-down or off. The Power-Down Register allows
0
the host to manage the AMC7832 power dissipation. When not
0
required, the ADC, internal reference, reference buffer amplifiers,
and any of the DACs can be put into an inactive low-power mode
0
to reduce current drain from the supply. The bits in the Power-
0
Down Register control this power-down function. Set the
0
respective bit to '1' to activate the corresponding function.
