Abstract

This paper describes the typical specifications and features of a novel low‐cost and high‐performance universal transducer interface (UTI). The easy‐to‐use interface enables fast prototyping of systems with capacitive sensors, platinum resistors, thermistors, resistive bridges and potentiometers. It is shown that a high accuracy and reliability can be obtained by applying a combination of advanced techniques, such as, auto‐calibration, advanced chopping and dynamic element matching. Examples of smart sensor systems, using the UTI and the popular microcontrollers, Intel 87C51FX and PIC16C73, have been presented.
