DAC712
A
0
is the enable control for the DATA INPUT LATCH. A
1
is the enable for the D/A LATCH. WR is used to strobe data
into latches enabled by A
0
, and A
1
. Refer to the block
diagram of Figure 1 and to Timing Diagram on page 3.
CLR sets the INPUT DATA LATCH to all zero and the
D/A LATCH to a code that gives bipolar 0V at the D/A
output.
SINGLE-BUFFERED OPERATION
To operate the DAC712 interface as a single-buffered latch,
the DATA INPUT LATCH is permanently enabled by
connecting A
0
to DCOM. If A
1
is not used to enable the
D/A, it should be connected to DCOM also. For this mode
of operation, the width of WR will need to be at least 80ns
minimum to pass data through the DATA INPUT LATCH
and into the D/A LATCH.
TRANSPARENT INTERFACE
The digital interface of the DAC712 can be made transpar-
ent by asserting A
O
, A
1
, and WR LOW, and asserting CLR
HIGH.
For no external adjustments, pins 4 and 6 are not connected.
External resistors R
1
- R
are standard
±
1% values. Range of
adjustment at least
±
0.3% FSR.
