12 or 14 bit ADC ?

Question

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.

I hope that you mean "rate gyros". ;-) Why don't you use a dsPIC with 12-bit ADC on-board? Best regards, Spehro Pefhany-- "it's the network..."                          "The Journey is the reward"             Info for manufacturers:  software/hardware/analog  Info for designers:

Ooops ;-)Good suggestion with the Pic. I will check that out.

under $6 in production quantity. I look at the 48 k flash version andthe features include on board I2C, onboard flash and micro9chiups softwaresupport is really good even with small quantities are involved.Don

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!
