CHAPTER 6

Simplified Design with Serial-Interface DAC

This chapter is devoted to simplified-design approaches for a typical DAC with three-wire serial interface. 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 bipolar output circuit.

6.1 General Description of DAC

Figure 6-1 shows the functional block diagram and pin configuration for a DAC (a MAX512/513). This IC contains three 8-bit, voltage-output DACs (DAC A, DAC B, DAC C). Output buffer-amplifiers for DAC A and DAC B ...
