• RE: ADN4650 unused Input pin

    Hi,

    The simplest option is probably to connect Din+ to Vdd1 and Din- to GND1; this will prevent any chattering from the unused input.

    If the input is potentially unused but might also be connected to a driver, then a biasing network of pull-up to Vdd1…

  • ADN4650 Θjc( Junction-to-Case)

    Hi,

    My customers are considering ADN 4650.

    In the data sheet, ΘJA is specified, but ΘJC is not listed.

    How much ΘJC's are there?

    Should I look for materials on the site below?
    I do not know the package code and STYLE LEAD COUNT ...

  • Using ADN4650 for Isolating TMDS

    Thank you for reading below my inquiry.

    I'd like to use ADN4650 for Isolating TMDS (of HDMI by mainboard in computer), but ADN4650 is for isolating LVDS.

    I found that TMDS's electrical specification is CML.

    So, I need to converting circuits both…

  • ADN4650 refresh pulse and min data rate

    The ADN4650 data sheet mentions that periodic decoder refresh pulses are issued in the absence of input transitions for more than 1us. For an input signal with a period of 1us will the refresh pulses cause any issue? The data sheet only mentions a maximum…

  • ADN4650 cable specification can be used

    Hi,

        I using ADN4650 for LVDS application , In datasheet it is mentioned that the cable can be used for a few meters. What is the maximum cable length can be used and what type of cable can be used.?

  • The Creepage of ADN4650 LVDS isolator chip

    For medical device, it is required that the LVDS isolator chip provides 8mm creepage distance for two means of protection. I just found on ADN4650 datasheet, 20-lead SOIC package provides 7.8mm. 

    I am not quite sure if this chip meet the 8mm requirement…

  • DOES ADN4650 ISOLATOR must be inputted NRZ data?

    ADN4650 datasheet中提到了,其能接收600Mbps的NRZ数据,那么是否说,非NRZ的差分数据,这款芯片没法正常工作?
    我们预期使用这款芯片进行视频数据的隔离。如果必须得是NRZ数据,那么这是由于icoupler技术本身的限制,还是别的?我看ADI这边像I2C ,SPI等的icoupler器件都可以的,没有说需要NRZ。望解答,多谢您;

  • LVDS隔离芯片ADN4650的问题

    采集通道使用的是TI的ADS1675,如下图:

    由于是多路采集,需要进行隔离处理,如果焊接芯片用漆包线把输入和输出连起来,采集正常,焊接了芯片

    输入正弦波时采集信号出现的问题如下图:

    第一路是把隔离芯片输入和输出两边地连起来,采集正常,后面的四路是正常没有进行连接,采集信号有误。

    请问这是什么原因造成的,我需要隔离时采集正常,现在不行。

  • RE: 4/26/16: Ubiquitous Measurement and Control with LVDS Isolators

    The primary difference between ADN4650 and ADN4651/ADN4652 is the channel directionality. ADN4650 has two isolated LVDS channels in the same direction (two transmit or two receive channels). ADN4651 or ADN4652 by contrast have one channel each direction…
