• RE: AD4001 and AD4005 differences

    Hi, 

    Apologies for missing this item. We cannot really disclosed directly regarding the internal design. But in general the part are both tested and has a guaranteed performance based on their timing specifications. So if you want a faster throughput you…

  • AD4001/4003采样率可以设置吗?

    打算采用AD400系列的adc芯片,考虑到前端电路有建立时间,且ADC最大采样率要小于建立时间的倒数。但是看到datasheet里面没有提及是否可以设置采样率,只说Turbo模式下最大2Msps,正常模式1.5Msps,那要是想设置1Msps该怎么办呢?

  • AD4001无法正确驱动

    问题描述:

             1、FPGA驱动AD4001 ,3线Turbo模式,时序要求已经满足,但是输出不正常。

             2、已经按照spec中的说明,将spi_clk 设置为100Mhz(spec要求spi_clk大于70Mhz,但是有同事用单片机验证,spi_clk未达到70Mhz,ad4001也能正常工作,为何FPGA按照规格书给出                       spi_clk,反而不能正常工作。)。但是SDI信号线上面电平无变化。

             3、设置AD4001工作在turbo模式下,需要将寄存器bit1设置为1…

  • AD-4001 Sending Consistently Incorrect Data over SPI

    Short Version: 

    I am having issues getting the AD-4001 to communicate via SPI. I am receiving consistently incorrect data that varies depending on the input voltage. This incorrect data is consistent across several trials, but does not scale correctly…

  • Adaq4001 70 mhz clock requriment for spi

    Hi,

    I am planning to use  ADAQ4001, but it requires mininum 70MHz spi clock, Most of the microcontroller on the market support up to 30Mhz. I didn't see higher. Do you have any microcontroller recommendation for me which is compatible with ADAQ 4001?…

  • RE: 關於AD7380 with ADA4940 如何設計 ADC driver for sensing +- 5V signals?

    Hi Alee,

    謝謝您的指點與建議:
    是這樣的,先前的設計使用AD4001 搭配AD4940,這次將AD4001替換為AD7380想說AD4940維持原先設計.

    可能在Ref 電源上需要重新計算與調配電阻值:

    Orignal AD4001

    Ref = 4.096V

    VCM =2.048V

    Gain=0.8x

    sensing +- 5V signals

  • 關於AD7380 的 typical circuit application 是否可用 Single-Ended to differential Conversion with a Fully Differential Amplifier模式設計?

    Hi 
    Q1.假設 dual-channel 只用到1個其中ch-A ,則 Pin14 SDOB/ALERT 是否需要預留GPIO控制或是可floating?
    Q2.先前用AD4001替換為AD7380,而 AD7380應用上否可以參考AD4001 Single-Ended to differential Conversion with a Fully Differential Amplifier方式設計?
    AD7380 typical reference circuit 看起來為Multiple…

  • RMS Current Control Based on LTC1968

    Dear Team,

     

    I want to make current control via MOSFET based on LTC1968. The load will be full wave rectified sinusoidal ( not filtered ) and frequency will be max 400hz.

    My design is in the attachement.

    1. I have used U1-LTC1968 and U2-LT1782 for RMS to…
