• ADA4817-1　Power Down

    Hi,

    My customers are considering ADA 4817-1.

    So I got a question.
    It is about operation in the Power Down state.

    #1  Is the input pin High-Z (high impedance)?

    #2  Does the current leak from the input pin?

    Best regards

  • ADA4817-1/2

    Hello, 

    I am looking for a buffer (Analog) with the following requirements: 

    1) Input voltage range: 0V to 0.9V 

    2) Fq: ~100MHz to 200MHz 

    3) Iq, Noise: We don't really care about it 

    4) VDD: We can provide any VDD between 0.9V to 3.3V (Or may be…

  • ADA4817-1 Input impedance change

    Hi,

    My customers are considering using ADA 4817-1.

    So I got a question.

    Does the input impedance vary with frequency?

    If it changes, how will it change?

  • ADA4817-1 output -> inverting input capacitance

    Hi all,

    I'm prototyping a low-noise photodiode frontend using the ADA4817-1 with 2 MΩ transimpedance gain.

    Despite considerable efforts to reduce feedback capacitance, I can't seem to get more than ~730 kHz bandwidth (-3 dB). Using the updated SPICE…

  • ADA4817用作跨阻放大器的问题

    准备利用ADA4817作为一个跨阻放大器进行电流电压转换，考虑到没有电流源，只能利用电压信号源作为输入，具体电路如下 仿真可见输出可达到1.5V的幅值，但是实际测试的时候，按照该图进行连接，在经过第一个电阻后的点进行测试，得到的波形如图 ，然后在输出利用示波器50欧姆的探头进行测试，只有很小的一点放大 ，而且每个正负输出都有一个-4V左右的偏压，不知什么原因，是不是原理图存在问题。
