The outputs of all DAC channels can be driven to a predefined value stored in the Preset register by driving the

PRE input low. The PRE input is asynchronous to the clock.

PD

: Full device power down

0 = normal

1 = power down

DO

: Digital output enable

0 = disable

1 = enable

IM

: Input mode

0 = straight binary

1 = twos complement

X

: Reserved

If DOUT is enabled, the data input on DIN is output on DOUT with a 16-cycle delay. That makes it possible to

daisy-chain multiple DACs on one serial bus.

In power-down mode, the amplifiers of the selected DAC pair within the device are disabled and the total power

consumption of the device is significantly reduced. Power-down mode of a specific DAC pair can be selected by

setting the PXY bit within the data word to 1.
