• ADA4091-2



    I'm developing my circuit by using this RRIO dual op amp ADA4091-2.


    My input supply is a single supply of 18V and 20V. In my circuit i have used two per of this op amp ADA4091-2.


    I had read through the datasheet of ADA4091-2 the…

  • ADA4091-2 Immunity Test Questions

    I have the technical questions on EFT/B immunity (IEC 61000-4-4) fail at 4kV through the input power supply of 24Vdc common line.

    We isolated the failure is caused by the ADA4091-2 because if i change to the existing part of op amp it will pass the…

  • Understanding the ADA4091-4 Input protection circuitry

    I have a circuit design which has an op amp with +/-15V rails feeding into an ADA4091-4 on 0->3.3V. There is 9.4k between the 2 parts of the circuit. Is this sufficient to protect the 4091 in light of an over voltage condition, or will it fail immediately…

    My JPEG saga continue...

    I am using a BF561 single core to compress a 640x480 YUV 4:2:2 image into JPEG format, employing the ADI JPEG Library tools.  I am getting very poor performance compared with the reference results from the Spec Sheet.  The Spec…

  • ADV7842 4:2:2 DDR mode, ADV7393: Stanag3350 support?  (2)

    Hello Dave,

    I am facing problems with replies to your answer, so I am oppening a new dicussion with the same title.

    Please clarify your answer regarding STANAG support:

    2) As I understand it, this is the same as RS-343A/EIA-343A and none of our parts…

  • LTC6804-2 and LTC6811-2 reference voltage 1 and 2 at 0V.


    I installed 2x LTC6811-2 and then 1x LTC6804-2 on the same board and I don't have any voltage reference output at anytime. The functional diagram in the datasheets shows that VREF1 should be always present as it's generated from V+. VREF2 is not…

  • 2*2 MIMO setup


    Iam interested in implementing a MIMO 2*2 scenario where i will use 2 fpgas (1 as the transmitter and 1 as the receiver) where each one  will be connected with one AD-FMCOMMS3-EBZ.
    So the setup will be :
    FPGA_1 + AD-FMCOMMS3-EBZ_1 =Base stati…
