Do chip (IC) based gyroscopes tell you your pitch/roll angle or just the rate of change?

and do any under £40 (or $60 [I know that's not the conversion rate]) not do that thing where they creep back to the rest position… or is there a way to fix this (turning it on and off periodically?) What I really need to be able to do is poll it from a microcontroller to get the current orientation when I need it… will one of these http://www.analog.com/en/mems-and-sensors/imems-gyroscopes/products/index.html do that?

Unfortunately, I am interested in building a similar gadget, and I have yet to find an IC gyroscope which indicates absolute position. They all indicate rate of change, which is why the signal goes back to zero when the rotation ceases.

    be more specific, pitch and roll are two different attitudes, and one causes a secondary effect on the other.
    Yes all gyroscopes suffer from lag or even topple at the extreme; but less if its through an acceleration error.

    What do you require the gyroscope for?
