DESCRIPTION…

The SP9840 and SP9843 are general purpose octal DACs in a single package. The SP9840

features eight individual reference inputs, while the SP9843 provides four pair of voltage

reference inputs. Both parts feature 5MHz bandwidth, four–quadrant multiplication, and a three–

wire serial interface. Other features include midscale preset, programmable signal inversion and

low power dissipation from a single +5V supply. Devices are available in commercial and

industrial temperature ranges.
