Title: EXTENDING THE CAPABILITIES OF AD694 TRANSMITTER IN BRIDGE CONNECTED SENSOR APPLICATIONS
Keywords: transmitter AD694, bridge measurement schematics

Abstract: The 4-20mA analog current interface has a wide application in industrial electronics because of high signal/noise ratio, especially in high noise environment. The interest in this interface doesn’t decrease over the years. A proof of this is the development of new ICs such as AD693, AD694 and XTR101 as well as embedding extra digital communication capabilities (for example the HART protocol, some HONEYWELL solutions etc.). This paper examines the subject of using the AD694 transmitter for converting the voltage of bridge connected sensor into current. It is proposed a three-wire interfa
