• RE: AD8045 Replacement


    Which AD8045 pin out are you considering?
    Is it the SOIC or the LFCSP?

    Also, the exposed paddle can be tied to your -Vs (negative supply if you are suing split supply and ground, if you are using single supply) or can be left floating.

    Thanks and regards…

  • AD8045 PSpice model

    Hi, I was trying to use the .cir model of the AD8045.

    --- By manually adding the library to the simulation profile I was able to make the design recognizing this device.

    -- Then, I tried to perform AC simulations, but I got the following error, where…

  • AD8045 spice model noise


    I am tring to do noise simulation with the AD8045 spice model.

    In ADISimPe the noise at 100KHz is 5.6nV/rtHz and not the 3nV/rtHz as told in the datasheet.

    I also imported the spice model in TINA from TI and the noise at 100KHz is 6.3nV/rtH…

  • Pspice model for AD8045


    Can anyone help with a 'working' Pspice model for AD8045? The one i downloaded form the website wont worjk for some reason. When i tried to simulate a simple design with it, i got this error message ' unknown parameter'.


  • AD8045 input bias current simulation

    Hi everyone!

      I simulate peak detector circuit form well known Horowitz & Hill book. I use LTSpice for simulation. I use AD8045 op amp. According to data sheet AD8045 has input bias current of 6.3uA max, but in the simulation results I observe current…

  • Spice model ad8045 temperature behavior

    I encounter problems with the spice model of the AD8045.

    It only works well with a temperature of 27 deg in spice.

    Will there be an update for the AD8045 spice model with also good noise figures?

    (Look at my post: "AD8045 spice model noise" form 26…

  • Better opamp then the AD8045


    Is there an opamp avalible that has the same spec's as the AD8045 but has a better noise figure like the AD8099 and must be unity gain stable 

    The AD8045 is over ten years old design. I would expect that somthing better must be out there…
