• Suggest to response time below 5ms for Capacitance-to-digital converters?

    Dear Sir,

    Because AD7152 is last time buy but customer is looking for fast response time which is less than 5ms or below.

    Does AD7152 have next generation product or could you give me advise ,tks!

  • AD7152 faster?

    Hi,

    I am currently working on a project to measure the capacitance in a relatively fast signal. I came across AD7152 and bought the development board. Working on a single channel, I can get a sampling frequency of 200Hz, however, I would like to get…

  • Looking for a AD7152 replacement

    Hi,

     

    I am currently working with the Eval-AD7152EBZ.

    I am using this board to measure pressure/weight by using a variable capacitor

    This works nice but I want to make more of these pressure sensors on the same I2C bus.

    But the with the AD7152 it…

  • Sensor Design for CDC

    Hello,

    I'm in the process of gathering information for designing the sensor for one of the capacitance digital converters like the AD7152. I'm looking to build a system that will measure the moisture in soil, so I need the measure the capacitance of…

  • RE: AD7745 External Excitation

    Hi there,

      

    the way the AD7745 is designed, it is not possible to use
    external excitation sources.

    The excitation source is not only to provide voltage levels, it
    also controls and synchronises the CDC measurement. In application note AN-1055
    on page…

  • RE: micron resolution capacitive proximity sensor

    The capacitive proximity sensors described in AD714x AppNote 830 are contact-less.

    What I'm unsure about is the achievable precision (distance, repeatable) with

    capacitive proximity sensors (AD714x) or Cap2Dig converters (AD715x/AD774x).

    I'll try…

  • Help: Choose a Capacitive-to Digital Converter

    Hi all,

        I am looking for a Capacitive to Digital converter of which the sampling frequency is bigger than 1KHz and the Conversion frequency is bigger than the sampling frequency and the resolution should be in fF level.Does someone have a good advice…

  • [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?
