| Abstract: | A new series of precision constant current source ICs-4DH series capable of being floating in circuits, both the current and the current temperature coefficient of which can be continuously adjusted, has been widely applied to various solid state transducers and other electronic circuits. Its principle is introduced. Some application examples of the devices used as a precision current reference, a precision voltage reference or a temperature compensation current source in temperature and pressure measurement circuits have also been given. Good results achieved. |
