• RE: quad opamp, isolation amplifier

    What are your supply rails? The LM747 will tolerate 22V supplies, which is more than most opamps will take.

    The AD8513, AD8674 and OP470 may be worth a look as they all have better performance. I don't know about Mil spec though.

  • 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…
