• Can't find Comparator AD790 in ADIsimPE Library

    Original Question: Can't find Comparator AD790 in ADIsimPE Library by ghussini

    How can I simulate AD790 if it's not in the library and AD website does not have spice model?

  • Operating range of the AD790

    I have read the AD790 datasheet.
    It is a question about the operating range of the AD790.
    The AD790 data sheet says "Dual? 15 V Supply Operation".
    And the AD 790 data sheet says "ABSOLUTE MAXIMUM RATINGS Supply Voltage ± 18 V".
    The AD790…

  • RE: AD790 3.3V Logic Supply ?

    Hi jcasey,

    Thank you for your interest on the AD790. We're currently checking the possibility of the AD790 for supporting  +3.3V logic and if we would be able to release a new grade or new product that could handle this condition. May we ask what specific…

  • 关于AD790的锁存引脚造成电流过大的问题

    上面是其中文手册的写法。

    我现在的用法是±15V供电，Vlogic为5V。

    我将锁存脚直接接到5V，上电发现，AD790的温度突然就升了上去，而从我的供电电源也看到，我的5V电源输出电流一下就达到了最大负荷电流。当我在锁存脚和5V之间加入一个3K电阻的时候，ad790和电源电流都正常了。

    可问题是，我见到过一个实际的电路，它确实是直接将5V接到了锁存脚，而且我也测试过，它并没用我这种温升快且电流过大的问题。

    我想问下ADI的工程师，当双电源供电时，AD790J的锁存脚如果直接接正逻辑电源…

  • 关于AD790的接法，为什么正向输入有个1.2v的直流电平？？




    按照图中的接法，C15过来的信号到了AD790的2脚后就会加在一个1.2v的电平上，不懂

    难道是TTL的门，要下拉吗？

    搞不明白啊，谁能帮忙科普一下

  • RE: Converting Sine wave (Input = bipolar +/- 2.5 Vpp @ 10MHz) to Square wave (Output= unipolar 0 to +5V)

    Hi William,

    You could look into AD790 particularly Figure 11 as well to implement a sine to square wave using a 5V single supply only.
