    HI Osman,

    Below is a list comparing the specifications of a few zero-drift, high precision op-amps that may be of interest.

    The device you mention above offers a GBW of 2.7-MHz. Depending on your GBW requirement you could select the OPAx182 (5-MHz) or OPAx188 (2-MHz). 

    All of the devices below offer very low offset and very low offset drift.

    The devices are available on single, dual or quad versions on different packages. 

    Please let us know if you have questions.

    Thank you and Best Regards,

    Luis
