Summarize: 

AZ 4-20mA Current Loop Isolation Interface IC provides signal receive and transmittal on a single chip. The ceramic hermetic hybrid package contains an electromagnetic coupled converter and current modulate. The very low input equivalent impendence allows the input voltage can be up to an ultra-wide range, so that it is able to meet the requirements for no distortion in long-distance signal transmission under the circumstance of no outside connecting power. The internal ceramic PCB, printed impendence and new Isolation technologies allow the IC for the 3KVDC insulated voltage and meets the industrial level for the extremely poor temperature, humidity and shaking conditions. These specifications make the AZ 4-20mA Current Loop Isolation Interface IC very easy to use, as well as providing compact for PCB board.
