integrated unity gain amplifier for driving null offset adjustment reference input

Hello to everybody,

I am looking for an i.c. with both an instrumentation amplifier and an (unity gain) op-amp for driving the reference input of the former in order to adjust the offset voltage. Does Analog Devices offer such an i.c.? Thanks.

  • Hi Cordon,

    We do have instrumentation amplifier with opamps in single package that you may want to look at which are the AD8295 and AD8231.

    May I know what applications are you dealing into and if the above inamps can meet your spec requirements?

    Don't  hesitate to ask me if you have any other questions or if you need further assistance.

    Best regards,
    Emman

  • Hello Emman,

    I have waited to be noticed in my email message box for an answer. I have to measure a current by means of a shunt in a variable temperature environment in which the amount of offset voltage is significant. Also, I want to use as few components as possible. I think that AD8295 meets my expectations.

    Thank you for your answer.

    Best regards.
