• Problem with the calibration of ad7755

    Hello

    I am a student and working on a project to measure the DC energy and power ICs AD7755 and I want to ask how to calibrate the integrated circuit I see that different combinations of outputs S0 and S1 and SCF to obtain a different value of the measurement…

  • 【技术支持】AD7755的pspice仿真模型

    您好,我在做项目的过程中会用到贵公司的AD7755芯片,目前在仿真阶段,希望贵公司可以提供该芯片的spice模型,谢谢!

    同时,我想咨询一下该芯片是否还在生产,是否可以检测直流电压电流,谢谢!

  • RE: 这11大应用领域,你在里面么?

    我最关注的领域是:能源;

    最关注的ADI产品是:ADE7816

        想当年ADDI公司推出的AD7755计量芯片,虽然价格高,但是性能绝对一流,面对国家智能电网改造,很多国内的芯片公司也开始做专门的计量芯片,但是芯片的性能与AD7755是无法相比的。AD7755是一种高准确度电能测量芯片,其技术指标超过了IEC1036准确度的指标要求,ADS只在ADC和基准源中使用模拟电路,所有其他信号处理都是数字电路,加上独特的采样算法,使得AD7755在恶劣的环境下仍然能保持极高的准确度和长期稳定性。虽然现在AD7755已经停产…

  • Current transformer specifications?

    Sir i'm doing a project on energy meter using AD7755 . As i have to use a CT, i wanted to know the specifications of CT and also i wanted to know also where is that CT available...???

  • RE: ADE7763 VRMS read SPI

    I think your grounding of V1P signal has caused the problem. Kindly have a look at the attached schematic for an example of a shunt connection on a single-phase energy meter based on AD7755. I hope this is helpful.

  • ADE7755 Implementation

    I want to use ADE7755 for measuring power of an appliance/bulb. Under application notes I found a circuit for implementing a watt-hour meter using AD7755.

  • RE: ADE7753 current sensors

    Hi Silviaing,

    The ground connection is on the phase because in a single phase metering application with a shunt, the ADE7753 is floating on the line voltage and therfore the ground connection is on the phase . On the evaluation board there is then isolation…
