    Heyy

    I am trying to achieve cap touch using AD7142. But the results shows overflows everytime. Anyone provide some sample values for configuring AD7142.

    Hello

    Im working on ad7142 for proximity detection. Can any one please provide the equation to map the output CDC code to corresponding capacitance value?

  • AD7142

    Heyy

    I am working with AD7142 for proximity detection. But still I cannot achieve it correctly because of the wrong register configurations. Any one can provide a sample code for this?  I am resolving the same issue for the last 5 months. Any one please…

  • AD7142: Signature capture

    Is it possible for the AD7142 to be used with a touch glass ?

    Is it possible to use the AD7142 for signature capture ?

     

    The AD7142 can function through a certain thickness of glass (a few mm).

    I assume that for signature capture, it…

    I am using a single Cin connected to positive CDC input. I have written the powerup sequence as shown below

    //bank2//

    AD7142_WRITE(0x00,0x80,0x3f,0xfe);

    AD7142_WRITE(0x00,0x81,0xff,0xff);

  • AD7142 Capacitance Range?


    Hi all,

            I am working on a capacitance measurement project where i am planning to use AD7142,

            I am confused in range which i can measure.

            Here CIN Input Range is ±2pf  , paracestic capacitance is 40pf.

           So what is the range???

    Hello All


    I am trying to interface an AD7142ACPZ-1500RL7 to my Arduino Uno. I can't find any resources/references for designing the breakout board for this SMD. In fact I cant even find the footprint of this IC in the EAGLE CAD library. (Referred Analog…

  • AD7142的几个问题

    问题1:AD7142测量电容的原理是什么呢?它是利用充电放大法还是测量复阻抗的方法呢?

    问题2:AD7142的INx内部结构是什么样的,是不是输入阻抗为0呢?采用互阻放大器吗?

    我想要用AD7142测量一个PCB的电容,但是PCB离控制器有10cm,而且导线的形状是可以变化的,想要在SCR和INx的信号线上外包金属来屏蔽,这样可以吗?
