    我用的是14通道的ad824,下一级还是ad824

  • RE: SPICE model of AD8657

    Hi Akira,

    I had a quick run of AD8657 and AD824 DC parameters on LTSPICE, both offset voltage are within the datasheet spec which is 350uV for AD8657 and 100uV for AD824.

    Please see below for my test setup and simulation results.

    Josh,

      I forgot to add that the OP400 product page does point out that the AD824, a much newer part, might be a better choice.

  • AD744电荷放大自激

    电荷放大如上图所示,实际测量中出现自激现象,RC滞后补偿和将R4变为1K已经尝试过,无法消除自激现象,自激波形近似三角波,峰峰值正负5V。这是什么原因,如何解决。为什么AD824不会出现自激现象

  • RE: AD824有两路不用,该如何处理

    把不用的运放接入电路弊大于利,增加了功耗,并且会对信号链产生一定的影响(运放的失真和噪声不至于比导线还小吧),至于延时要看运放的带宽和压摆。一般不会这么做的。

  • 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…
