Non-linearity Compensation Method for Temperature Transducer AD590

Focusing on the problem of non-linearity occurs in the application of the Integrated Circuit Temperature Transducer AD590; a method to compensate non-linearity is presented in this paper. A brief introduction to the features,principles of AD590 and the reasons of non-linearity error are given with emphasis on the methods of non-linearity compensation in environment temperature detection. The experiments results show that the methods of non-linearity compensation have the advantages of low cost, low error and high precision.
