DI-188 ADC Resolution Calculator

How much ADC Resolution Do You Really Need for your Measurements

The bit value of an analog-to-digital converter (ADC) refers directly to its resolution. The resolution determines how finely it slices its full-scale measurement range, or in other words, the smallest change in the input signal that it can theoretically measure (ignoring noise). Use the calculator below to determine if the DI-188 has enough ADC resolution to meet your application requirements. Review the blog post How Much ADC Resolution Do You Really Need? for more information.
