This
device
This DAC uses a double-buffered 3-wire serial
interface
that
is
compatible
MICROWIRE, and most DSP interface standards.
In addition, a serial data out pin (SDO) allows for
daisy-chaining when multiple packages are used.
Data readback allows the user to read the contents of
the DAC register via the SDO pin. On power-up, the
internal shift register and latches are filled with zeroes
and the DAC outputs are at zero scale.

The DAC7811 offers excellent 4-quadrant multipli-
cation characteristics, with large signal multiplying
bandwidth of 10 MHz. The applied external reference
input voltage (V
) determines the full-scale output
current. An integrated feedback resistor (R
