• ADA4927-2 Layout suggestion

    I am going to design a pcb with the ADA4927-2 OpAmp, so i would ask for a good layout example or suggestion.

    Are there any evalboard-files or something to see a good layout example for this opamp?

    Best Regards


  • ADA4927-2 to drive an AD9652


    I have some doubts and questions about using an ADA4927-2 to drive an AD9652. First of all is wether that would require symmetric supplies or if it will suffice with +5V single supply. The optimum input Vcm for the AD9652 is 2V and the output range…

  • RE: HMC336 control logic

    HI S.ilke,

    I was thinking for proposing ADA4927-1/ADA4927-2 with the following configuration.

    Please help to know whether this configuration can be used toggling the switch control or not.



  • ADA4927-1 / ADA4927-2 power-down feature below 0°C

    Good day!

    Our device should work with wide temperature range, but in datasheet at ADA4927-1 / ADA4927-2 we've found that:

    The power-down feature should not be used in applications in which the ambient temperature falls below 0°C. Contact sales for…

  • RE: How to connect ADRF6806 to the ADCs

    Here is an article I wrote on the ADA4927 driving the LTC2185 (a 16 bit part).  This might help you with your design.

    Uncompromising Linearity from the LTC2185 and ADA4927-1 

  • Uncompromising Linearity from the LTC2185 and ADA4927-1

    The LTC2185 is a 125Msps 16-bit ADC with excellent noise and linearity performance while only consuming 185mW per channel. It is ideal for demanding low power applications that require excellent AC performance. A high performance ADC like the LTC2185…

  • RE: AD9257 ADC driver and VCM output buffer recommendations

    Here at the university of Edinburgh, we are saving the same problem.

    We are using the ADA4927-2 to drive AC coupled signals into the AD9257 40MS/s ADC. The ADA4927-2 has an input resistance of 5k typical. We have 'n' of these being driven by a single…

  • The circuit for bidirectional signal (ADA4927 output impedance @ power down)


    I would like to send interactive signal on the one differential signal line.

    The direction of signal would control by switch.

    This signal is up to 20MHz.

    (The signal amplitude is about 1Vpp temporarily )

    For example, if we design this circuit…

  • RE: how to reconcile the capacitive sensor with a close differential amplifier?

    Hi Dmitrii,


    1. Is your sensor in IC form, is it a voltage output device? If yes:

    2. What is its output impedance? High or low? If it has a high output impedance, use ADA4817-2, the first amplifier buffer configured and the other one with…
