back low for the next data word to be loaded
in. This pin also disables the SCK pin
internally when pulled high.
Power-Down Mode
The DAC have three Software-
Selectable Power-Down Output
Impedances (1k Ohm, 100k Ohm) as
additional safety feature for
applications that drive transducers or
valves. The power down can be done
with loading the control word with
1111 (C0 to C3). The selection of the
Output Impedance of DAC is
controlled by the last 5 bits. See Table
1 and Table 2 for details of operation
of this function.
Power-On Reset
There is a power-on reset on board
that will clear the contents of all the
latches to all 0s on power-up and the
DAC voltage output will go to
ground.
