Daisy chain AD7706

Hi Drew,

Neither the AD7706 or the AD7710 parts can be daisychained. Using the product selection table for ADC's located at http://www.analog.com/en/analog-to-digital-converters/ad-converters/products/index.html and the three requirements of 16-bit, daisy chaining and DIP package the only device which has all three is the AD977(A). The datasheet is located at http://www.analog.com/static/imported-files/data_sheets/AD977_977A.pdf and contains information on how to daisy chain these parts. Please review the datasheet to deteremine if this part is suitable for your application. This part is quite old however, as are the AD7706 and AD7710, and I'm not sure if there is still an evaluation board still available for the AD977(A). Let me know if you wish to choose this part and I can check the status of the evaluation board.

The requirement of a DIP package is the most limiting factor for your choice here. There are other parts which have daisy chain capablility but not in a DIP package. For example please have a look at the AD7980 (http://www.analog.com/en/analog-to-digital-converters/ad-converters/ad7980/products/product.html). This part is relatively new and does have an evaluation board available.

Can you give me some more information on your application and perhaps we can refine your requirements and find a suitable part for you ?

Regards,

Rob
