Question
How many analogue inputs does the EVAL-AD7655EDZ evaluation board have? The generic user guide for AD76XXEDZ shows only two analogue inputs, whereasthe AD7655 ADC has four analogue inputs. Is there a separate user guide for EVAL-AD7655EDZ?
Answer
The evaluation board that covers the AD7655 only has two analog inputs. There are several AD76xx products that are covered by this evaluation board.The configuration of the board is determined by the link connections to match the desired input range and type of the user. The user most likelycould attach 4 inputs by taking advantage of these link connections, but there are only two SMB connectors on board.
There is no user guide specific to the AD7655, The latest revision of the generic user guide is available on the AD7655 product page on:www.analog.com/AD7655
