• 基础+干货,MEMS技术给讲全、讲透了!

    传感器技术哪家强?MEMS技术当为王。。。哈哈,没错,MEMS传感器应用几乎无处不在了哦,不是么,拆开你的手机看看呗,少说也有那么三五个,哈哈~话说,常常有小伙伴问到小编关于MEMS的各种基础概念,今天偶得一篇好文章,必须贴出来分享下,从概念到工艺,讲透了,觉得好的筒子们请帮忙转发哦,点个赞呗,(*^__^*) ……

    MEMS是Microelectromechanical systems的简称,即微机电系统/微机械/微系统。虽然对其有辣么陌生,但是在我们生活中早已无处不在,几乎近期的智能手机、健身手环…

  • Linux driver for ad7888

    I see there is linux kernel driver support for the ad7887, but the very similar ad7888 does not seem to have a driver anywhere.  Can I use the same driver?  Can I read all 8 channels using this driver, since the 7887 is only a 2 channel device?

  • RE: IIO framework for AD7321 driver

    Hi,

    We currently do not have a IIO driver for the AD7321. But there is a driver for the AD7887 which has a similar interface, the main difference is the placement of the bits in configuration register. You should be able to adopt it to work with the…

    Hi Kd0704,

       

       Sorry missed the thread. In the future, if you have questions related ADC or precision ADC in particular, please start a thread in the Precision ADC community.

       On your question on where to start, You should have a board or set up using…

  • RE: add sysfs trigger

    Now I set all unused pins to "-1".  When kernel start I see this message:

  • 关于AD22293Z经过ADXL203推荐电路后的比例因子

    我使用AD22293Z,也就是ADXL203的5g版本,按照ADXL203参考设计(CN-0189)文档中的图1搭建了一个试验用电路,用5V供电传感器。按照ADXL203的DataSheet的表1所说,AD22293Z的灵敏度是312mV/g,我在参考电路的左端,也就是传感器端用万用表测量,比例因子的确在312mV/g左右。但在参考电路的右端,也就是AD7887的输入端测量,发现传感器在0g时,电压的确是1.7V左右;但传感器在1g是,电压并不是1.7+3.3/5.0×0.312=1.90592V…

  • Please suggest high-speed ADC (5 - 50 MSPS) for sampling AD8318

    Hi All,

    I have an AD8318 based circuit which samples a pulsed RF signal with a pulsewidth on the order of 1 usec.  I would like to use an ADC to convert the analog output of the AD8318 to digital so it can be read and processed by an FPGA.  The design…
