• LT1997-2 Distortion Specs

    Hello!

    In a LT1997-2 datasheet I see image on a page 1 with a THD spec on 1 kHz and on page 18 there is a Distortion section with a general words: "The LT1997-2 features excellent distortion performance when the internal op amp is operating in the normal…

    thanks for help

  • LT1997-3 Rn、Rp Calculation

    Hello

    I tried to make a circuit equation like the attached file because I didn't know what to put as Rp, Rn to verify the formula of note 9 in the data sheet.

    Vos,out=(Vos x NOSEGAIN) + Ios x 22.5K + Ib x 22.5K x (1 - Rp/Rn)

    However, the above formula…

  • Behavior of LT1997(-3) in LTSpice

    I am evaluating an LT1997(-3) as a high-side current sense amp in a single-polarity system, up to 100+VDC.

    I modeled it in LTSpice, and am seeing unexpected results.

    The model doesn't seem to work with a single +5V supply, and gain configurations other…

  • RE: Script file of ADV7611 for 24bit SDR 4:2:2 Mode 2 output

    Hi,

       In general the drive strength and trace impedance must match to reduce ringing

      The ringing is caused by a mis-match in the drive strength and trace impedance.  Try lowering the drive strength for the pin output or increasing the series resistor.Note…

  • JPEG Processing - 4:2:2 v 4:2:0?

    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…

    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.

    Hello,

    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

    Hello,

    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 :
