Signal Conditioning for a Sigma-Delta ADC in Industrial Multichannel Data Acquisition Systems

This application note helps the designer of high-performance, multichannel data acquisition systems (DAS) configure the proper interface between industrial sensors and high-performance ADCs. The example used is a power-grid monitoring system. The note also explains advantages of the MAX11040K ADC's sigma-delta architecture, and how to select the proper schematic and components to achieve optimum system performance.
