Universal Transducer Interface(UTI)
Wang Li · 2001
The Universal Transducer Interface (UTI)is troduced in this paper.It is a kind of interface IC with high integration level,μp compatibility,high applicability and auto-calibration.The UTI is a complete front end for many types of passive sensors,such as resistors,resistive bridge and capacitive sensors.The three signal technique is used to eliminate the effect of unknown offset and unknown gain in a linear system.
