  • RE: LTspice simulation of ADA4898

    Hello Kaos,

    I did simulate this component on LTSpice :

    Open your .CIR file with LTSPICE, then here :

    .subckt ADA4898    1    2    99    50    4

    Right click on ADA4898 and click on create symbol.

    This will create your component. You can also rename your pin (wisely…

  • ADA4898-2: Differential voltage for the unpowered ADA4898-2

    Does the ADA4898-2 have back to back protection diodes at the input?
    I'm afraid that without these diodes we may surpass the +-1.5v differential
    mode input voltage at the absolute maximum ratings in an unpowered state.

  • ADA4898 bandwidth

    Hello,

    I would want to know if the ADA4898 have enough bandwidth to amplify (simple non inverter stage) with a gain of 40 for large signal (+/-4V) with +/-6V power supply rails.  The bandwidth required for my application is 350kHz, Could you please confirm…

  • ADA4898-2: Maximum voltage in an unpowered state

    This circuit is part of a magnetic field analyser. A new application requires
    us to double the sensor range.  

    The worst case scenario is that the user exposes our analyser without power to
    fields greater that its measurement range..…
