• AD8655: Current noise density

    I couldn't find the information about the input current noise characteristics
    (?fA/?Hz ) and input impedance characteristics of AD8655/8656 on the website
    and also on the data sheet. How can I achieve this information?

     

    We do not…
  • What is the input referred current noise for the AD8655/6?

    What is the input referred current noise for the AD8655/6?

     

    On CMOS op amps, the current noise is very, very low. It’s usually negligible.
    That’s why you don’t see it on the datasheet. The current noise for the AD8665
    is in only…

  • Noise on AD8655 Output

    I am using AD8655 as LNA for piezo transducer signal conditioning. I am getting a strange output frequency spectrum, lots of spikes every 2200Hz, roughly.

    The low-pass and high-pass roll-off is accomplished further down the signal chain. The above spectrum…

  • AD8655带宽问题

    以下是我设计的一个单电源同相放大器,放大倍数为:25倍,但是带宽只有 8KHZ, 跟数据表给出的参考 带宽不符合,请问大神有什么解决的办法。

  • AD8655 TIA unexpected noise

    for my thesis work I have built a TIA based on the AD8655. It is a quite standard TIA, with a transimpedance gain of 1M and a bandwidth of 100kHz. For this application the noise of the complete circuit is critical, so I designed and simulated this…
  • AD8655 parameters modeled?

    Hi, 

     

    I'm using ADIsimPE to model a circuit built around the AD8655 op-amp. Particularly I want to know if the model takes into account the input capacitance and input resistance of the device.

     

    From the application note, I understood that the models…
