SP9841
SP9841 is BiCMOS DAC manufactured by Sipex Corporation.
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 mercial and industrial temperature ranges.
