• LTC3850 Variants

    What exactly is the difference between LTC3850EGN and LTC3850IGN? There is no hint in the data sheet about this. Both variants have the same temperature range specification of -40°C...+85°C. When I started with this device 12 years ago, there was a consumer…

  • 关于在LT4363-2及LTC4364-2中的Retry Duty Cycle问题?

    敬启者,您好:

    在选择使用LT4363-2及LTC4364-2中有一个参数Retry Duty Cycle;

    关于Retry Duty Cycle,我的理解是:

    假定T1为Cctmr电容开始充电到MOS管关闭所需时间,Tcool为冷却时间;

    Retry Duty Cycle=T1/(T1+Tcool) * 100%

    LT4363-2:Less Than 1% Retry Duty Cycle During Faults, LT4363-2;

    LTC4364-2:0.1% Retry Duty Cycle…

  • Pluto - 2 Rx and 2 Tx using MATLAB

    Hi,

    I would like to setup the SDR Pluto to operate in 2 Tx and 2 Rx mode.

    I have followed the steps in the following video : https://www.youtube.com/watch?v=ph0Kv4SgSuI

    However, I am unsure how to setup and control the 2nd transmitter or receiver. 

  • RE: ADA4940-2, issue on creating 2 differential signals around 0V

    Hi, 

    With a bit late, thanks for this suggestion.

    By applying -0.2V to R3, this circuits can convert 0 to 0.4V to a balanced -0.2 to 0.2V .

    It has been checked on the eval board.

  • ADV7611 YCbCr 4:2:2 SDR issue

    I am trying to configure ADV7611 to output 1280x1024 video in 16-bit SDR ITU-R BT.656 4:2:2 Mode 0.

    In free-run mode with blue background I get "0xFF00, 0x0000, 0xFF00, 0x0000..." pixel data, but it is 1280 LLC-period wide DE window between HSyncs…

  • LTC3300-2

    Hello everyone,

    I want to realize a communication between an LTC6804-2 and LTC3300-2 using the SPI that the first IC can generate.

    The problem is that the LTC3300-2 do not respond to the command I send to it, in particular I tried to send a 'Readback…

  • A question regarding LTM4671 parallel 2+2 mode.

    Hi ADI support team. I use LTM4671 in my new design. The datasheet of this device is here: www.analog.com/.../LTM4671.pdf I wonder whether there are two mistakes in the figure2 of datasheet? For 2+2 parallel application, I think PHMODE0 must connect to…

  • RE: LTC6948-2 ,I can read from LTC6948-2,but I cant write in LTC6948-2 register.

    Hi,

    Are you using the LTC6948 eval board, FracNWizard, and DC2026 (USB to SPI board)?  Or are you trying to write to the part using your own software and hardware?  Can you send a plot of your SCLK, SDI and !CS signals, so I can look at the timing?

    To write…
