PRODUCTION DATA
One example to take advantage of performance is the implementation of multiplexed data acquisition front end for multiple input sensors. Applications such as analog input modules for programmable logic controllers (PLCs), data acquisition (DAQ), and semiconductor test systems commonly need to monitor multiple signals into a single ADC channel. The multiple inputs can come from different system voltages being monitored, or environmental sensors such as temperature or humidity. Figure 9-1 shows a simplified example of monitoring multiple inputs into a single ADC using a multiplexer.
