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.
