• Output drive current for ADA4661-2 and ADA4666-2


    How high of an output current can the ADA4661-2 and ADA4666-2 drive?


    The ADA4661-2 and ADA4666-2 are capable of driving output currents up to 30 mA with only 1V of dropout voltage. However, the usable output load current drive is limited to…

  • about EPAD of ADA4666-2


    I need some help.

    As below picture picked from the datasheet. it said EPAD can connect to V- or leave floating, does ADA4666-2 also work if connected EPAD to GND?

    I mistakenly connected EPAD and GND, it sees the consumption of current rised.

    I will…

  • ADA4666-2: only reading 57 kohm input resistance (to V-). Part damaged?

    Dear ADI,

            I'm using the ADA4666-2 to operate as the error amplifier in a constant current/constant voltage feedback loop. The constant current loop has adjustable gain.

    However, I don't get the expected voltage at pin 3 of the ADA4666-2. After I…

  • Difference between the ADA4661-2 and ADA4666-2

    What is the major difference between the ADA4661-2 and ADA4666-2?


    The ADA4661-2 is designed to have a lower offset voltage (correspondingly,
    higher common mode rejection) than the ADA4666-2. The ADA4661-2 uses Analog
    Devices Inc. patented…

    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…

  • RE: Clock distribution to 2 DDSs (9913) and 2 ADCs (AD7769)


    the AD9577 is a good choice if the 40 MHz clocks to the AD9913 may not be phase aligned to the 40 MHz clocks to the AD7769.

    The AD9577 has two PLLs that are not recommended to work at the same frequency because  the jitter performance is degraded …

  • 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.
