• Spice Model AD8624 OK?

    Hello,

    When I simulate the AD8624 with a 500 Ohm load resistor, the output is limited to 0.4V.

    The circuit is a differential amplifier with gain 1 using 10kOhm resistors plus a 500Ohm load.

    The design will have only +/-5 supply voltage.

    I have attached…

  • RE: Universal Definition for "No Connect" or "NC"?

    Hi, David.

    Thank you for using ADI products. Regarding your question, the "NC" or "No connect" pins have no internal connections. These pins are provision for improvement for the part's derivative. This means that the "NC" pins of AD8624 in LFCSP maybe…

    Hi Harry

    Thanks but I was asking about the AD8264 quad differential VGA Amplifier not the AD8624?

    Thanks

  • RE: Need amplifier like OP497 but smaller size

    Hi Kole,

    Do you already have a board fabricated? Can your board accommodate something slightly wider? I believe the AD8624 will perform very closely to the OP497. The size of the IC is 4.4mmx5mm, please see Figure 62 on the datasheet. If you require…

  • 脑电信号采集时多通道间的相互干扰的问题

    尊敬的工程师:

             您好,我用AD8624作为采集EEG信号前面电路时,发现如果其他3个通道悬空,1个通道接触良好时,这个通道会受到其他3个通道 的干扰,如果将这3个通道短接并接地,这个接触良好的通道就好多了,这样我想有个问题就是,在正常采集时,这几个通道间会不会有互相串扰的问题。谢谢。

           另外我想知道互相串扰产生原因,如果能成放大器内部解释更好,

  • RE: 这11大应用领域,你在里面么?

    最关注能源领域,因为我的工作是做光伏并网逆变器的。

    最关注AD8624运放,它是一款四通、低失调、高输入阻抗的运放,在设计中用于逆变器的光伏输入对大地电阻的检测。

  • RE: AD8220 output voltage

    Hi Scott,

    Thanks for your comments. I confess I've never paid attention to the diamond plots before (not being too sure how to interpret them). From your comment I can now see the answer to part 2 of my question. With a difference input of 40mV (when…

  • Noise optimizing AD8599 &&

    Good day,

    I have a task to optimize noise in BW 10Hz - 10kHz.

    Voltage gain shall be around 20..50. OA connected directly to source of signal,

    which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,

    where R1 connected…
