• OP97 Single Power Supply

    Hi All,

    OP97 does not accept a single power supply? I tested it as I-V conversion function as attached.

    Connecting 4 pin to -15V power, the OP97 output voltage changes corresponding to amount of light (OP97 works normally), but the output voltage does…

  • RE: OP97 / OP07 spice models

    The OP297 is the dual version of the OP97 so the OP297.cir model should work. I think the only difference might be that the dual version does not pinout the external compensation pin. If you are using that feature of the OP97 you might have difficulty…

  • RE: Difference between OP97EPZ and OP97FPZ

    Look at the spec table columns.  OP97E and OP97F.

    E is lower offset.  Get the F for experiments.


  • OP97: Overvoltage protection

    Does the OP97 have overvoltage protection and for how long is it protected?


    The o/p of the OP97 includes circuitry that limits the current o/p to generally
    about 10mAmps, when the o/p is shorted to gnd or to either supply. Therefore

  • RE: AD5445 single supply application


    Please see above additional questions,


    LTC6078 has 25uV maximum offset voltage, as same as OP97

    I simulated in SPICE and it should work.

    AD8066 cannot be used per your answer above.

    I simulated in SPICE and it should work.

  • AD5542A pin description

    I plan to use AD5542A (16 pin TSSOP) in my design. Now I find the pin description on its datasheet is not compatible with the schematic of its evaluation board (ad5542_ug). 

    Could you verify the pin description of AD5542A?

  • 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…

  • RE: Medical ECG low power/low distortion DIP Op amp

    Hi, Hoagim2013.

    A right leg drive amplifier is purposely used for common-mode bias and for noise cancellation especially the 50/60Hz. A high CMRR and and low noise amplifier would suit this application. OP90 and OP193, which Oliver had suggested, are…
