摘要
热电偶放大器AD595将仪器放大器和热电偶冷接头补偿器全部集成在一块单片芯片上,产生一个10mV/℃的输出。采用AD595设计一个测量温度系统。该系统由热电偶放大器AD595、AD转换芯片AD574以及单片机P89C61X2BN和键盘显示芯片Zl G7290组成,用于光集成芯片的温度测量,也可以用于其他温度测量场合。
The AD595 is a complete instrumentation amplifier with thermocouple cold junction compensation integrated on a monolithic chip,which produces a high level (10 mV/℃) output directly from a thermocouple signal. A temperature measuring system, which consists of AD595 and A/D converter AD574 ,MCU P89C61X2BN and Zlg7290 as well. It is intended to measure the temperature of photon - integrated - chips and could be used in many other applications.
