• ADE7858A freezes the measurements

    Hello,

    I am in the same case as:  ADE7858A Gets Stucks 

    I have a board with 4 ICs. One ADE7880A and three ADE7858A. I communicate with SPI instead of I2C which is most robust versus interferences.

    The board is working 5 months and about 7 times ADE7858A stops…

  • ADE7858A Gets Stucks

    Hello,

    We have used ADE7858A in our product for energy measurement purpose. In few devices on field we have observed that all the electrical parameter value gets stuck and frequency value becomes 409.6 Hz. After some diagnostics we have found that RSTDONE…

  • ADE7858A AGND DGND Neutral Connection

    I am using ADE7858A for my application. ADE7858A is interfaced with an microcontroller over I2C protocol. I have connected AGND, DGND and neutral together. I was bit worried about these connections and have following questions:-

    1.) Is it ok if I don…

  • ADE7858A硬件连接!

    1.ADE7858A裸露焊盘exposed pad应不应该接AGND?(英文手册说一定要接AGND,中文手册说不要有任何电气的连接那只是加强机械强度和散热的?)  

    2.ADE7858A采用的晶振一定是要16.384MHz的晶振吗?16.32MHz的行吗?

    3.我的功率表电压输入用电阻分压的方式,对于3相4线还行,对于3相3线这种没有中线和地线的现场应用该如何接线,没有参考点7858A如何采样啊,软件上又该如何调节呢?

  • ADE7854A, ADE7858A, ADE7868A, ADE7878A

    Hi all,

    I'm designing power meter and analyzer. I consider using one of the above mentioned metering ICs.

    I was looking at the datasheet for detailed technical specifications, however the datasheet was little confusing.

    I need to have an exact…

  • ADE7858A input protection

    Hi Prof,

    We use ADE7858A in our system. The input range of ADE7858A is +/-0.5V. I hope to know if there are some very simple input protection components to protect the circuit that match this energy management chip, such as TVS/MOVs.

    Thanks advance

  • ADE7858A Checksum calculation

    Hello,

    I'm trying to calculate checksum in software to verify it against the one calculated by the metering IC.

    I have received a spreadsheet of registers used for calculating checksum for ADE7858A and have a couple of questions about it.

    I’ll…

  • RE: ADE7858A Phase B calibration in 3 wire delta system

    Hi Aaron, 

    Thanks for the elaborate explanation!

    I do understand that the value in the BVRMS register in case of 3 wire delta system is Vac(RMS) which I believe is computed by the DSP in ADE7858A.

    What I don't understand is the difference in magnitude…

  • ADE7858A protection

    Hi everyone,

     

    I have a technical question about hardware issues:

    Analog inputs get damaged soon in testing, first 1voltage input got damaged and then
    all of the inputs did and I lost AVDD, all happened in my lab in normal conditions,
    can a pair of 1N4148…
