Fresno: 16bit 0 to 10V input isolated AFE

Keywords:analogue-to-digital converters  field programmable gate arrays  microcontrollers 

Low resolution and low input voltage analogue-to-digital converters (ADCs) are integrated in many of today's field programmable gate arrays (FPGAs) and microcontrollers. However, they fall short on meeting the needs of industrial control and industrial automation applications that require higher resolutions and higher input voltages. The Fresno (MAXREFDES11#) sub-system reference design is a 16bit high-accuracy industrial analogue front end (AFE) that accepts 0 to 10V signals and features isolated power and data—all integrated into a small form factor.

This document explains how the Fresno (MAXREFDES11#) sub-system reference design meets the higher resolution and higher voltage needs of industrial control and industrial automation applications. Hardware and firmware design files as well as FFTs and histograms from lab measurements are provided.
