Precision demands new level of data conversion accuracy

Atsushi Kawamoto, Jesper Steensgaard, Mark Thoren and Heemin Yang, Linear Technology. In each case, these systems push the boundaries of signal processing and require ppm (parts per million) accuracy. They can incorporate wide-dynamic-range sensors, high-order control loops, and the highest performance IC components. At the core of many precision industrial systems is an ADC (analogue to digital converter!). It plays a pivotal role, translating signals from the analogue domain to digital for digital signal processing. The accuracy and performance of the ADC often defines the accuracy and performance of the overall system.
