| Abstract: | The MAX1457 is a special sensor signal processor optimized for piezoresistive sensor calibration and compensation. Achieving a total error factor within 0.1% of the sensor's repeatability errors, the MAX1457 compensates temperature errors and non-linearity of silicon piezoresistive sensors. Many steps are needed for compensating temperature errors of sensors and a development device is needed for this operation. The work principle and compensation process of MAX1457 are discussed in this article. A development device is designed, it has friendly interface, and automatic optimized procedure and can simplify the process of sensor compensation. |
