• RE: Can I left the PD pin of ADA4857-1 unconnected for normal operation?

    I found these in ADA4861-3, which states that if PD function is not used, it is best to connect them to -VS (negative supply). I wonder whether this also applied to ADA4857-1.

  • RE: ADA4861 Spice Model

    Hi harryh,

      I've added the bypass cap and reduced the voltage divider resistances to 1k rather than 100k to give a 2.5V bias on the + node of the ADA4861. 

    I'm quite confident with the rest of the circuitry because as soon as I add a -5V rail to…

  • RE: Analog Component Video Splitter

    There is no specific device to create a 1 x 3 YCbCr buffer.

    A 1 x 3 buffer can be easily implemented with many op-amps like the ADA4861-3 along with some circuit design.  In the datasheet, Figure 50 shows how to implement 3 buffers.  Just tie the 3 inputs…

  • RE: about AD828 Video OPAMP


    Hi Kou,

    I checked our Opamp portfolio and you may want to consider the ADA4861-3 and ADA4850-2 which are both video amplifiers. I still encourage you to specify your opamp requirement (ie, bandwidth, power supply, slew rate...) so we can choose…

  • RE: 3-Phase 4-wire in to 3-Phase 3 Wire

    Good Afternoon

    The ADE7878 can be configured to accept multiple different configurations including 3 phase 4 wire and 3 phase 3 wire wye and delta.  Our FAQ:  AN-639 that is available on our website has detailed diagrams of each connection on pages 12…

  • ADUC843BCPZ32-3


    咨询下单片机ADUC843BCPZ32-3 的技术问题:

    1.)参照DATASHEET, PSEN脚在代码执行模式下应该输出高,实际输出为低(0.005V左右)。


    3.) 代码运行过程中,PSEN管脚可否通过电阻上拉到电源?



  • 3-phase PFC and LT8312

    We have a legacy power supply that has to be redesigned from the ground up. The input is 115 Volts, 400 Hz, four wire, three phase Wye connected. The desired output s a single DC voltage to feed downstream DC-DC converters, which will be designed separately…

  • ADE7880 - 3 phase 3 wire delta configuration


    As per the ADE7880 datasheet pg. 43, in three phase three wire delta configuration, Phase B active, reactive and apparent powers are 0.

    So, I would like to know if there is a way to find out the Phase B power data in three wire delta configuration…

  • AD9371 TES invalidargument 3


    When I clicked on "Connect" from TES (AD9371), a window erros shown in below:

    InvalidArgument=Value of '3' is not valid for 'index'. 

    Parameter name: index 

    Please help me to solve this issue.

    thank you.
