• 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…

  • 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…

  • Q&A on ADXL203EB (Dual Axis Accelerometer Evaluation Board)

    1. ADXL203 Accelerometer itself is marked 33878203xlI382, Is the accelerometer
    supposed to have a zero G bias of 0V or 2.5V?

    2. At zero G upon measurement with an oscilloscope my accelerometer produces 1V
    and the self test feature produces…
  • 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…

  • RE: AD7357 how to check the DC Accuracy in worst case condition

    Hi Kevin,

    I have attached some list of ADC that were Automotive Qualified. Do you have specific paramater that you are looking for an ADC? like Throughput rate, no. of channels, or Resolution.

    You can also visit the Analog Devices website and filter…
