  • Request the spice model of ADA4830

    Dear Analog,

    Could you please provide the spice model for ADA4830-1? I want to simulate CN-0273 using different first stage op-amp, and I also want to test some ADC driver scheme using dual ADA4830 or ADA4830-2.

    Thanks!

  • Differential video transmission with ADA4433-1 and ADA4830-1

    Hello,


    Thanks for providing the spice model of both ADA4433-1 and the ADA4830(-1).

    I'm trying to design a DC coupled differential transmission system using the ADA4433-1 and the ADA4830.

    The overall gain from input (ADA4433-1) to output (ADA4830…

  • ADA4830-1 in pseudo-differential mode... input trace geometry?

    Hi,..I'm using difference amp ADA4830-1 in conjunction with decoder ADV7180 (Circuit Note CN-0263), to receive a CBVS video signal.  My question has to do with the ADA4830 input trace geometry on my circuit board.  Given that I'll be connecting the…

  • 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…

  • 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.

    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…

  • ADM1176-2 reset

    I am using the ADM1176-2 (latching) part on a new PCB design.  I am wondering if setting the SWOFF bit over I2C can reset the latch state the same as toggling the ON pin?  The datasheet isn't entirely clear on this aspect--on Page 16 Table 11, it states…

  • AD7175-2 Unipolar Resolution

    Hi,

    I am looking to use the AD7175-2 with an external 5V reference to sample a unipolar differential signal (0 to 5V range); however I was concerned with possible resolution loss compared to bipolar operation (-2.5V to 2.5V range), as some of the other…
