Renesas example for ad7176-2

Hello,

 

        I'm trying to use the demo board for the 7176-2 (EVAL-AD7176-2SDZ) in standalone mode with an external 4-wire connection. Following the tutorial http://wiki.analog.com/resources/tools-software/uc-drivers/renesas/ad7176, same Renesas demo board, connecting according to instructions, everything works and compiles fine. But when applying a ~1V DC signal to channel 1 (or any other channel), I only get a 0V measurement on all channels.

 

        Can you confirm that the jumpers LK5-9 are to be removed? Further, I should be able to use the demo board in stand-along mode like that without the CB1Z motherboard, correct? All the solder links should be fine in default mode? Lastly, I should not need to connect any reference voltage and such to J7, correct?

 

        Sorry about the elementary questions, but I've been trying for quite a bit to get this to work, this is just to check the bases and eliminate connection issues.

 

Thanks alot!
