    here are my requirements -
    I need to connect an oscillator to excite a sensor
    simultaneously, I need to collect the signal from 3 other sensors and amplify it (ideally using one amp).
    Lastly, of the 4 sensors, I need to be able to switch the excitation source.

    This is not a book/class but rather a real life problem so any help ideas or direction is appreciated. I just don't know what's out there.

    Thank you!

    If signal levels are compatable, try using 2 4066 IC's, one to switch oscillator ,one to connect sensor to amplifier. If they are to be switched in a continuous sequence, drive 4066's with 4017 or 4022 & 555 as clock.
