• AD5170 Wiper Resistance

    Hello,

    I think I understand the concept of wiper resistance, but the AD5170 datasheet doesn't seem very clear.

    According to specs listed on page 4, RWB (Wiper Resistance…

  • AD5170经常坏

    AD5170BRM10原理图如下,

    VDD2_Red 接5V,A,W,B分别接在下图R+ ,抽头,和R-上。

    数字电位器是10K,标号2指向的电阻10K,这两个电阻的分压Vctrl送到芯片里。



    我用示波器测量Vctrl在开机的时候波形如下


    AD5170BRM10刚换上的时候是好的,用一段时间,机器开关几次后,AD5170BRM10就失效了。

    Hello Alkrojen,

    I’m sorry, EngineerZone doesn’t currently provide a support community for the AD5170 digitial potentiometer.  

    To get support on this product, I would suggest submitting your question to the Analog Devices support team in your region…

  • [征文] IN118的基准源用AD的芯片,上面写着D6B,困饶我很久了 AD5312


    这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?
