• Boosting AD8642 output current

    I'm testing a design in which I need to do a current to voltage conversion. The current ranges from picoamperes to 100mA (both positive and negative), so I use 4 different resistors and a switch to select each of them. I filter the corresponding signal…

  • RE: Low input bias current. Which one to choose?

    Some of the other choices are:

    ADA4610-2 if you need a dual

    AD820, AD822

    AD8641, AD8642

    AD8610, AD8620

    AD8510, and ADA4610-2

    All of these are stable at gain of 1 for your voltage follower

  • RE: AD8066用哪个芯片可以替换

    关于测量光电二极管的应用,最主要的参数就是要看运放的偏置电路Ibias以及带宽。还有运放的输入范围。

    对于您的要求,您可以考虑AD8642. Ibias和功耗都比较小。带宽也可以满足您的要求。

    Rookie,

      When I do a sim on the power supply, you have no attenuation with R20 and C20 until you get past

    15 kHz.  Try increasing R20 to 100 ohms and C20 to 10 uF.  Would also help to put a small ceramic

    (0.001-0.01uF) across C20.

    The AD8541 is CMOS…

  • 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…

    这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?
