Soon after the discovery of the basic counting ADC architectures (see Tutorial MT-026) it was realized that much greater accuracy could be obtained using a combination of integrating and counting techniques. This led to the development of high accuracy dual-slope, triple-slope, and quad-slope ADCs. Although the proliferation of high resolution sigma-delta ADCs has made integrating architectures somewhat less popular, they are still used in a variety of precision applications such as digital voltmeters, etc.
