一种新颖的数字宽范围测温电路

Development of new－style digital circuit used for measuring large－range temperature

采用AD590K双腿集成电路温度传感器进行大范围温度检测，用AD570S对传感器的输出进行数字量化（8bit），实现对温度大范围的数字化检测，具有大动态、高精度、体积小、高可靠等优点。

In this paper a new－type digital circuit is introduced with AD590K temperature sensor measuring large－range temperature and AD570S quantifying the output of the sensor． Moreover the circuit has such excellences as large dynamic range small volume high precision and reliability．
