![]() ![]() A common way to do that is to apply the analog voltage to one terminal of a comparator and trigger a binary counter which drives a DAC. ![]() ![]() HyperPhysics***** Electricity and magnetismĬonversion from analog to digital form inherently involves comparator action where the value of the analog voltage at some point in time is compared with some standard. It is typical for an ADC to use a digital-to-analog converter ( DAC) to determine one of the inputs to the comparator. The basic principle of operation is to use the comparator principle to determine whether or not to turn on a particular bit of the binary number output. This is a sample of the large number of analog-to-digital conversion methods. Analog to Digital Conversion Analog-to-Digital Conversion ![]()
