Description
After power-on or reset, all bits in the power-down register are
cleared to 0, and all the components controlled by this register
are either powered-down or off. The power-down register allows
the host to manage the AMC7836 power dissipation. When not
required, any of the DACs can be put into clamp mode and the
ADC and internal reference into an inactive low-power mode to
reduce current drain from the supply. The bits in the power-down
register control this power-down function. Set the respective bit
to 1 to activate the corresponding function.
