• AD8014

    AD8014可以用来做差分放大器设计吗,能输入差分,输出单端信号吗?

    AD8014可以输入两路差分信号使其输出一路单端信号吗?

  • RE: AD8014

    AD8014是双极性运放,其偏置电流为5uA,而示波器探头可以等效为1MR对地电阻,这样运放的偏置电流会流入到示波器的输入电阻上产生失调电压和噪声电压甚至是波动,所以正确的测量方法是示波器一般只测量低阻抗输出端,而不要测量高阻抗输入端。TL082是jfet型运放,其偏置电流低,一般是pA量级,可以很大程度的避免此问题。

  • AD8014 output voltage range

    Hi,

    I'm using the AD8014ARZ in as a buffer for my DAC output application.

    I see that in the datasheet there is a specification for output voltage: 1.1 to 3.9V

    But as my application demands, I want to get an output from 0V to 0.9V.

    So the question…

  • AD8014的带宽问题

    我用AD8014做同相放大器,放大倍数为10倍,输入信号为100KHz,幅值为100mv的正弦信号,可以正常放大,但是向其输入1MHz,100mv的正弦信号,只能放大不到5倍,但是数据手册里面 显示带宽为400MHz,请问是什么原因造成这种情况的呢?对比图放在下面。RF=1K欧姆,RG=120欧姆。

  • AD9834 + AD8014 DC return resistor

    I have an AC-coupled signal coming from an AD9834 fed into an AD8014 as shown below.  

    Do I need a DC return resistor to ground between C11 and U7 and, if so, what value should I use?

    My maximum output frequency will be 5 MHz, sine wave only.

    Thanks for…

  • Recommended feedback resistors for AD8014

    Hello,

    I want to use a AD8014 as a noninverting amplifer with either a gain of 12 or a gain of 50.

    The signal will have a bandwidth of f-3dB=6MHz.

    Can someone recommend a set of feedback resistor values for this application.

    Best Regards

  • AD8014阻抗匹配问题

    电路笔记CN-0304里面,请问如图所示,AD8014的输入端为啥没有做阻抗匹配呀?谢谢。

  • AD 9834生成正弦波问题咨询


      你好,我在用AD9834和AD8014生成正弦波时使用的是ADI公司提供的CN--0304电路,但这为什么它的频率仅仅到18Mhz(AD9834和AD8014自身的频率都远远比这个高),我希望的是可以达到30Mhz,使用这种电路可以吗?还有就是我不需要方波的输出,那么VIN引脚该如何处理,拉高、拉低都可以吗?
