9.3    Summary

Data converters, or specifically analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), play an important role in the design of data acquisition units in communication and microprocessor-based instrumentation systems. They include analog and digital building blocks and form the main interface component in mixed-signal processing systems (for some typical applications, see Table 9.1).
