• Strange Input Current in ADA4084-1

    Greetings.

    I am using the ADA4084-1 in a non-inverting, follower configuration in a data acquisition application.  The input is AC coupled.  At high input power levels, the input suddenly latches to a high value, and will stay there until the input RMS…

    Thank you so much Harry! I'll try ADA4084-1.

    Just change to an ADA4084-1, ADA4610-1, or AD8671 and the power dissipation will

    be a lot less.

  • ADA4084 SPICE Model

    Hello,

    I'm trying to use ADA4084 spice model inside of LTSpice. 

    However, I'm getting errors "Singular matrix: check node u7:82 Iteration No.1", where u7 is one of the ADA4084 instances. 

    I have read elsewhere online that LTSpice doesn…

  • ADA4084 characteristics

    Dear all,  

    I probably posted a message in the wrong forum. Please find below the question related to ADA4084

    Datasheet Table 3 specifies that at +/-5V, typical input impedance is [100KOhms||1.1pF]Differential and [200MOhms||2.5pF]Common mode.

    Are these…

    ADA4084-1 is next generation OP184; higher speed, less power, less money.

    Also see AN-940

    What is your sensor/source impedance?

    Yes, on +/-5V, the spec table only guarantees the Input Voltage Range (IVR) to be -2V to +3V

    so you are doing better than expected.  The ADA4084-1 is RR I/O.

    What temp range for the system?

    Rob,

      A lot of people have successfully used the 8237, so next time, post a question and let's figure out

    why it's not working for you.  For a good general purpose op amp that's RR I/O, I would use

    the ADA4084-1.  (or ADA4528-1, AD8615, etc…
