They can measure and store data collected from hundreds of channels simultaneously. However, the majority of systems con-tain from eight to 32 channels, typically in multiples of eight. By comparison, a simple voltmeter that can select a Measurement among several different ranges can be considered a data acquisition system, but the need to manually change voltage ranges and a lack of data storage hobbles its illustrates a simple data acquisition sys-tem consisting of a switching network (multiplexer) and an analog-to-digital converter (ADC). The main subject of this chapter, the instrumentation amplifier (IA), is placed between the multiplexer and ADC. The individual circuit blocks each have unique capabilities and limitations, which together define the system performance. The ADC is the last in a series of stages between the analog domain and the digitized Signal path.
