    Selecting the right accelerometer

    I will be giving power to my board using a 3V coin cell battery. Therefore I am looking for a low power solution. Tilt detection and motion detection are more important. its ok if tap detection cannot be done. Please suggest one of the ICs I had mentioned or any other alternative for my application.

    why opamp input track

    Physical mechanism that makes opamp input track each other: Opamp inputs track each other only in the case of negative feedback. In the other two configurations, positive feedback and open loop ,there is no virtual short between the two inputs of opamp. So one should first make this clear that...
