Understanding Single-Ended, Pseudo-Differential and Fully-Differential ADC Inputs

Abstract: Many of today's instrumentation and process control applications convert the analog output of a sensor for processing and/or storage using an analog-to-digital converter (ADC). For voltage input ADCs, three different input structure types exist: Single-Ended, Pseudo-Differential and Fully-Differential. This tutorial explains the differences, advantages and tradeoffs between the input types.
