  • AD7785温控方案准确度超标

    如图所示,采用AD7785,双极性配置,内部使用buffer并在初始化程序中做了0位校准和全量程校准,内部Gain=1,配置IOUT恒流源位210uA.。

    问题如下:

    1.设置210uA电流,实际使用万用表测试R37两端电压为3.8V以上。

    2.采用直流电阻箱模拟PT1000,设置1142.45欧电阻,实测1145左右。

    目前可知的是IOUT输出电压超过了ouput compliance范围,但是根据此电路测量方式可知与电流无关,且误差非固定的,随着PT1000阻值增大而增大。

    目前做了如下尝试…

    Hello,

     

    We are use the AD7785 in a Oxygen measurement system. At this time we manufactured ca. 600 pieces. At the last 100 we have problems with the precision of the AD7785.

     

    The problem is the value of the full scale register. The failed devices (ca…

    I’m trying to use the ad7793 device driver to control an ad7785 that is connected to our custom board. When we use the spidev driver it seems to work fine and we get valid data although we get one strange behavior. The Device ID that is returned when…
