  • 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.


    We usually model and…

  • 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…
