CHAPTER 4

Simplified Design with a Typical ADC

This chapter is devoted to simplified-design approaches for a typical ADC IC. All of the general design information in Chapters 1 through 3 applies to the examples in this chapter. However, each data-converter IC has special design requirements, all of which are discussed in detail. The circuits in this chapter can be used immediately the way they are or, by altering component values, as a basis for simplified design of similar data-converter applications. The chapter concludes with a fully isolated 12-bit ADC using serial-to-parallel conversion.

4.1 General Description of ADC

Figure 4-1 shows the functional block diagram and pin configuration for the ADC (a MAX187/189). This serial-bit IC operates ...
