This DAC utilizes data readback, allowing the user to read the
contents of the DAC register via the DB pins. Upon power-up,
the internal register and latches are filled with 0s, and the DAC
outputs are at zero scale.
As a result of manufacturing with a CMOS submicron process, this
part offers excellent four-quadrant multiplication characteristics,
with large-signal multiplying bandwidths of up to 10 MHz.
