12 or 14 bit ADC ?

  1. I am looking for a relatively cheap 12 or 14 bit analog-to-digital
    converter that I can use to read the output of three rat gyros at about
    100 to 200 samples per second.

    I would prefer a one chip solution to read all three of them, but low
    price is the major issue (sadly...). I will read the chip using a PIC,
    so any interface is fine, but SDI or I2C would waste the least amount of
    pins ;-)

    Any suggestions and shared experiences are greatly appreciated.

  2. I hope that you mean "rate gyros". ;-)
    Why don't you use a dsPIC with 12-bit ADC on-board?

  3. Ooops ;-)

    Good suggestion with the Pic. I will check that out.

  6. Very cool. Somehow I totally misinterpreted the 'ds' by confusing it
    with DSP. This is a great solution, looking at all the variation of this
    technology. I already found some chips I really like, plus I do have the
    whole PIC environment set up anyways.

    Thanks, guys, for "redirecting" me back to PICs instead of going the
    external component route!
