The ADC 5 Click Board™ is a device used to sample an analogue voltage on the input and convert it to digital information. In general, ADC (analogue to digital converters) are the most commonly used devices for converting the voltage signals into information, which can be then processed in the digital domain. There are many types of ADC converters commercially available. They can vary in bit depth, sample rate, used approximation algorithm (SAR, delta-sigma..) and so on. Those attributes affect how accurately the sampled voltage will be translated into the digital world.
