Simplified Design with Parallel-Input DAC
This chapter is devoted to simplified-design approaches for a typical DAC with parallel input. All the general design information in Chapters 1 through 3 applies to the examples in this chapter. The circuits in this chapter can be used immediately the way they are or, with alterations in component values, as a basis for simplified design of similar data-converter applications. The chapter concludes with a typical four-quadrant multiplication circuit.
7.1 General Description of DAC
Figure 7-1 shows the functional block diagram and pin configuration for the DAC (a MAX530). The IC is a low-power, 12-bit, voltage-output DAC that uses single +5-V or dual ±5-V supplies. The DAC has an on-chip voltage ...
