• RE: Design analysis of ADA4841-1

    Answers to your numbered questions below:

    1. With the range specified, the peak-peak voltage will be (4.974 - 0.029) = 4.945Vpp. This is equivalent to ~98.9% of the AD7942 input range (assuming VREF = 5V).
    Just be aware that these output swing numbers…

  • VCM voltage connected to IN+ of ADA4841

    Hi,

    I am using ADA4841 amplifier and AD7942 ADC  in my project. I was referring to the EVAL-AD7942-PMDZ evaluation kit. I would like to know why input common mode voltage is connected to IN+ pin of ADA4841 with capacitor and resisitor. Can someone please…

  • ADA4841-2YRZ Supply Voltages

    Hello! In datasheet i couldn't find information about maximum voltage between Vs- and Vs+. I suppose it should be 24 V, but have concern about it.

    I want to use OpAmp with -10V for Vs- and +5V for Vs+.

  • RE: ADA4841 Input voltage headroom

    Hi,

    We have Rail-to-Rail amplifiers and you can check through this link.
    One of the filtered parts is ADA4084 which operational from 3V to 30V.

    Thanks and regards!

  • ADA4841-1 0.1Hz to 10Hz noise

    Hello, 

    Are there any information available for ADA4841-1 about the voltage noise density vs. frequency in the range 0.1Hz to 10Hz?

    If not, are there information available about the 0.1Hz to 10Hz voltage noise (peak-peak)?

    I will use the ADA4841-1 as a…

  • ADA4841-2 管脚IN+,IN-一直有电压是什么原因？

  • ADA4841 Exposed Pad

    The datasheet for the ADA4841 says that the exposed paddle of the LFCSP package should be connected to ground (Figure 3 on first page).  In a split supply design is that Ground (0V) or is it the negative supply?

  • 發現ADA4841-2新的問題!!!!

    小弟起初在ADA4841-2的輸入端+IN跟-IN沒有接任何東西，當輸入端沒接電壓時，量到的是4.3V左右，

    之後在輸入端+IN跟-IN兩點並上10K電阻，當輸入端沒接電壓時，量到的是則變成0.03V左右，但它仍然沒辦法達到軌到軌，

    參考電壓在5V情況下，輸出電壓仍然只有4.3V。

    AD的專家們，麻煩幫忙一下，這問題困擾好久了，而且在datasheet上好像沒有說要在輸入端+IN跟-IN兩點並上電阻，

    該怎麼處理比較好呢??，謝謝大家的幫忙!!

  • Pluto - 2 Rx and 2 Tx using MATLAB

    Hi,

    I would like to setup the SDR Pluto to operate in 2 Tx and 2 Rx mode.

    I have followed the steps in the following video : https://www.youtube.com/watch?v=ph0Kv4SgSuI

    However, I am unsure how to setup and control the 2nd transmitter or receiver.
