• ADA4941-1

    Hi All,
    I am looking for OPAMP which can convert single ended signal to differential signal to drive the ADC which has differential input. I have selected ADA4941-1 and tested for -2 and +2 gain configurations which are mentioned in Figure 58 and Figure…

    Original Question: ADA4941-1 .cir by sss

    Hi all,

    Our customer tryed to simulate the ADA4941-1 with ADIsimPE.
    They downloaded the ADA4941 SPICE Macro Model from web linked page .

    But the error occured with following error massage.

  • ADA4941-1 introduces noise


    I am getting data from an AD7961 ADC with an ADA4941-1 in front as a single-ended-to-differential stage.

    I am getting a surprising noise of +/-2mV when I short the ADA input to ground. This noise goes down to +/-0.2mV if I skip the ADA4941-1…

  • Effects of external resistor on ADA4941

    Hi Neil,

    Thank you very much for your reply.

    The provided information is really helpful to me. As you suggested I have decided to use ADA4941( similar to ADA4940 ). I am using ADA4941 (single to differential converter) as similar to the architecture…

  • What the difference between the ADA4940-1 and the ADA4941-1?

    What is the difference between the ADA4940-1 and the ADA4941-1? They are both ADC drivers, but what distinguishes the two parts from each other?

  • ADA4941-1 opened input signal


    I am considering Sallen-Key, Low-Pass Filter like figure 54 on the datasheet.

    There is a situation that the input is opened.

    Then the output would be unstable.

    Should I put termination resistor?

    If yes, which value can I use?

    There is a little…

  • ADA4941-1 outputs in-phase... cause?


    while measuring  the specs of a measurement prtotype, where at the end a
    ADA4941 drives an AD7691, I noticed that the outpunts of the differential
    amplifier are in phase. I could not detect shorts and measuramnts were taken
    with and without…

  • RE: ADC Driver for AD7763

    Hi Andreas,

    ADA4941-1 could not handle Input Voltage of +10V since it is limited to an IVR of -4.8 V to 3.9 V. You will be needing an attenuator after the transducer to step down the voltage at a level acceptable by ADA4941.


  • RE: Can I use ADA4941-1 with bipolar input signals while unipolar power supply?

    Hi Andrey,

    Apologies for a delayed response.

    Yes you can use ADA4941-1 at bipolar inputs with single supply, PROVIDED that there is enough DC bias for the inputs. ADA4941-1 is guaranteed to work with an input common-mode voltage range of 0.2 to 3.9…
