The programmable multiple output generator provides the control signals for data converter ATE. Major performance criteria are simple, interfaces to a number of microprocessor systems, low power consumption, stable output timing relationships combined with a minimum of board space. For schematic simplicity only, one output circuit is shown in full. The monolithic HS7584 provides four current output DAC`s with four quadrant multiplication, individual reference input and a feedback resistor.

C is the value of Cl to C4 and R is the resistance of the DAC. With the four DACS on a single chip, the resistance matching is good, which results in stable timing relationships of ihe generator outputs. The output of ihe comparator A2 determines whether the constant current source provided by A3 and A4 is positive or negative.
