Re: Using EVAL-ADXRS624Z

Hi brsimon,

Please take a look at the ADXRS624 Functional Block Diagram on page 1 of the product datasheet. This figure shows the connections required in a typical application. Without seeing your setup, of course, it seems like you may be missing the connection of a +5V supply to VRATIO (pin 7 on the eval board). Ensure also that all of the required capacitors are in place.

Please give that a shot and let us know if it works.

Thanks,

Nitzan
