• 运放AD8001使用问题,急待解答

    目前正在使用AD8001,严格按照datasheet中给的电阻值,同相放大,10倍增益。

     

    我的电路结构 非常简单, 同相放大,同相端对地50欧姆,反相端2个电阻(50欧姆,470欧姆),这些基本是手册给的电路和电阻值,如果需要,我可以上传电路图。

     

    上电后,发现输出零点50mv,是不是有些偏大?

     

    输入正弦波信号,输出正弦波,放大倍数正确,但是 原来的50mv零点消失了。很奇怪。

     

    理论上,这个直流偏置或者称为零点,应该会叠加在正弦波输出,但是实际却没有, 是AD8001电流反馈放大器特有的特点吗…

  • Same function by using same pcb deign for AD8001&AD8000

    Hello Guys,

     

    We were testing on AD8001 and AD8000, and got good result. Now our engineers are design final circuits.There are several things need you help:

    1. I read ADI's user guide - UG-755, and got this evaluation board's pcb files. I checked…

  • RE: How to drive both AD8351 and AD8001 at a time with RF amplifer

    Do you want to drive the AD8351 and the AD8001 simultaneously? If so, you will need to use a power divider to split the power and feed it to both devices.

  • I need to design a balanced photodiode input transimpedance amplifier with 200 MHz.  Any suggestion of op amp?  Is AD8001 suitable?

    The AD8001 has no information on input pin differential and common mode input capacitance.  There is no open-loop gain/phase curve either.

    AD8001 can support single power supply circuit, so AD8001 can directly replace the single power supply circuit in ad812 data manual?

  • RE: What is the (noninverting) input impedance of AD8337?

    Hi Michael,

    Your AD8337 inquiry was referred to me, I am it's application engineer. The preamp of the AD8337 is similar to the AD8001, a class of amplifier characterized as current feedback. In terms of input impedance, the noninverting input behaves…

    Hi Atul,

    Figure 5 does match the data in Table 5. Please note that the graph is in log scale.

    These discussions would help in your layout considerations. AD8000&AD8001 PCB design issues and Same function by using same pcb design for AD8001&AD8000…
