HBE 18 Data can be loaded into the AD760 as straight binary, serial
data or as two 8-bit bytes. In serial mode, 16-bit or 18-bit data
can be used and the serial mode input format is pin selectable,
to be MSB or LSB first. This is made possible by three digital
input pins which have dual functions (Pins 12, 13, and 14). In
byte mode the user can similarly define whether the high byte or
low byte is loaded first. The serial output (SOUT) pin allows the
user to daisy chain several AD760s by shifting the data through
the input latch into the next DAC thus minimizing the number
of control lines required in a multiple DAC application. The
double buffered latch structure eliminates data skew errors and
provides for simultaneous updating of DACs in a multi-DAC
system.
The asynchronous CLR function can be configured to clear the
output to minus full-scale or midscale depending on the state of
Pin 17 when CLR is strobed. The AD760 also powers up with the REV. A
