• LTspice ADHV4702-1

    你好,

    我需要輸出+-60V/1Aout的1KHz Sine wave,所以選了ADHV4702-1加上LT1166來模擬,發現在一開始的時候,輸出端有個pulse出現,

    於是參考ADHV4702-1 datasheet內的TYPICAL APPLICATION CIRCUIT 模擬,但是輸出總是會有一個pulse出現.

    於是改成Unity-Gain Buffer,並且輸入端下地,依然輸出有一個pulse出現.

    請問該如何解掉這根pulse呢?謝謝.

  • EVAL-ADHV4702-1 using single power supply

    Dear Sir/Madam,

    I am trying to modifying the EVAL-ADHV4702-1 evaluation board to single power supply (0-220V) mode, to amplify a 0V-2V triangle voltage waveform to 0-200V voltage:

    1. For the power management part (the flyback converter on board), I am…

    I can't find any documentation for the 12-lead, 7 mm × 7 mm LFCSP on the Leadframe Chip Scale Package Design Center page. Is that documentation available for the package?

  • ADHV4702-1 Power drive current

    As shown in the figure, what is the minimum drive current of the VCC and VEE power supply pins?

  • ADHV4702-1 Eval Board Design Documentation?

    Are the PCB design files available for this eval board? That would be very helpful. Thanks.

  • 增加ADHV4702-1输出功率的问题

    大家好:

        使用ADHV4702驱动压电陶瓷,驱动功率不够.设计了如附件中ADHV4702_1.rar的电路.仿真没有问题.但实际电路中150V电压会进行输出短路保护.M2也会变得非常烫手.不知道是什么原因,请帮我分析改正.

  • 关于ADHV4702-1运算放大器的产品咨询

    我需要设计一个如图所示的电路,红色部分是一个等效压电驱动器,其中包含一个等效电容Cpea,图中电容CrCpea相等,利用反相放大器产生一个反相的电压Vc,可以抵消掉等效电容Cpea上的电荷Qd,从而提取到的准确值。

    但是存在一个问题,源电压Vc是交流电压,且振幅比较大,约有200V-300V左右,频率大约在2kHz-3kHz,我在贵公司网站上只看到了耐压值最高110VADHV4702-1运算放大器,不知道还有没有耐压值更高的运算放大器,或者替代的解决方案

    希望能在这里得到帮助…

  • RE: ADHV4702 high current output

    Hello PPeixoto.  It's hard to answer without some more information.  Can you tell us if you mean 120V peak, or peak-to-peak?  Also, what gain is the ADHV4702-1 used in?  It looks at first glance that the performance you need is a bit beyond the capability…
