Paper Abstract

The MAX1457 is a special sensor signal processor optimized for piezoresistibve sensor calibration and compensation. Smart compensation system is designed based on full study of MAX1457 principle. The scheme of compensation system is given. The software of smart compensation system developed by VC++ can run on any windows operating system. The parameters can be achieved automatically. Each step of compensation is guided by diagrams. The system is stabile and reliable, through field test. The issues of consistency, temperature shift and nonlinearity are solved by the system. An output error factor of silicon piezoresistive sensor is achieved within 0.2%.
