Acquiring data from sensors involves measurement and processing of real world analog voltages and currents. Typical devices used in the data acquisition signal chain are amplifiers, multiplexers, isolators, and ADC’s. In some cases measurement accuracy can be improved by providing an offset voltage via a DAC. System requirements for accuracy, bandwidth and input range dictate the selection of amplifiers and ADCs. A DSP or μ-controller is used to process the digital signals for display or analysis.
