MAXIM数据采集系统的方案
2013-08-20
基本特性:
MAX1358/MAX1359数据采集系统内置二极管结温度传感器,利用二极管的I-V特性测量温度,为了提高测量精度,Maxim器件将校准系数存储在数据采集系统内部,修正读数误差,以获得最高精度。
温度读数对应于二极管的实际结温,对于连续监测温度变化的系统,可以直接使用温度读数。对于需要获得封装外部温度的应用,需要对读数进行调整才能得到更准确的数值。
方案描述:
The serial port that will be used to communicate with the EV kit needs to be set. From the applications File menu, select the Connect menu item. The MAX1358 has a number of jumpers configured by default to quickly start using the EV kit.
