Using a 12-bit-resolution analog-to-digital converter (ADC) doesn’t indicate your system have 12-bit accuracy. Often, much towards the surprise and consternation of designers, a data-acquisition system will display lower overall performance than anticipated. When this is actually found after the initial prototype operate, a mad scramble for a higher-performance ADC ensues, and several days is spent reworking the style since the deadline for preproduction builds fast approaches. How it happened? What changed from the initial investigations? An extensive knowledge of ADC standards will expose subtleties very often induce less-than-desired results. Understanding ADC requirements will also help you in choosing the right ADC for the application.
We begin by starting our very own total system-performance demands. Each part inside the system may have an associated mistake; the aim is to keep consitently the full error below a particular limitation. Often the ADC is the key component in indication road, so we ought to be cautious to pick an appropriate equipment. When it comes down to ADC, let’s hypothetically say that the conversion-rate, user interface, power-supply, power-dissipation, input-range, and channel-count criteria are appropriate before we began the examination with the total program show.
