AD7321 or AD7327

Hi, 

I made some study for AD7321 for a while and I thought this chip could meet our requirement. But when I tried to purchase the evaluation board to perform a further evaluation, the system said that EVAL-AD7321 was not recommended for new designs and recommended EVAL-AD7327 for the new design.

I was wondering the recommendation is just for the evaluation boards or also including the chips? What's the difference between AD7321 and AD7327 except for the channels? Can I rely on the evaluation result from EVAL-AD7327 to make a decision that whether AD7321 is good for my application? My application only needs one input channel.

Thank you very much,

Cloud

    Hi Cloud,

    Yes this advice is just in relation to the eval-board itself. When the parts were transferred to our latest evaluation platform, the decision was made to create boards only for the AD7327/8/9.

    Other than channel count, functionality of the AD7321 is identical to the AD7327.
