DESCRIPTION…
The
SP9841
and
SP9842
are general purpose octal DACs in a single package. The
SP9841
features eight individual reference inputs, while the
SP9842
provides four pair of voltage
reference inputs. Both parts feature 6.3MHz bandwidth, two–quadrant multiplication, and a
three–wire serial interface. Other features include midscale preset, no signal inversion and low
power dissipation from a single +5V supply. Devices are available in commercial and industrial
temperature ranges.
