The programmable multiple output generator provides control signals for the data converter automated test equipment (ATE). Major performance criteria include simple interfaces with various microprocessor systems, low power consumption, stable output timing relationships, and minimal board space requirements. For schematic simplicity, only one output circuit is fully illustrated. The monolithic HS7584 features four current output digital-to-analog converters (DACs) with four-quadrant multiplication, individual reference inputs, and a feedback resistor. The values of capacitors C1 to C4 and the resistance of the DAC are denoted as C and R, respectively. With four DACs integrated on a single chip, resistance matching is optimized, leading to stable timing relationships for the generator outputs. The output of comparator A2 determines whether the constant current source provided by A3 and A4 is positive or negative.

The programmable multiple output generator is designed to efficiently provide control signals for data converter automated test equipment (ATE). Its architecture emphasizes compatibility with various microprocessor systems while maintaining low power consumption, which is critical for applications requiring energy-efficient operation. The design prioritizes stable output timing relationships, ensuring that the signals generated are reliable and consistent over time, which is vital for accurate data conversion.

The integration of four current output DACs within a single monolithic chip, specifically the HS7584, enhances performance by allowing for precise four-quadrant multiplication. Each DAC is equipped with individual reference inputs, facilitating greater flexibility in signal generation. The inclusion of a feedback resistor further optimizes the output characteristics, contributing to the overall stability of the system.

In terms of component values, capacitors C1 through C4 and the resistance of the DAC are crucial for defining the operational parameters of the output generator. The matching of resistance across the four DACs is particularly advantageous, as it minimizes discrepancies that could affect the timing relationships of the output signals. This matching is essential for applications where precise timing is necessary.

The functionality of the output generator is further enhanced by the comparator A2, which plays a pivotal role in determining the polarity of the constant current sources provided by A3 and A4. This configuration allows for dynamic adjustments to the output current, ensuring that the generator can adapt to varying operational conditions. The overall design, with its focus on simplicity and efficiency, makes it an effective solution for generating control signals in automated testing environments.The programmable multiple output generator provides the control signals for data converter ATE.
