AD2S99 and AD2S82A

Dear Sir/Mdm,

 

Please refer to page 6 of datasheet of AD2S99 (you can find the datasheet here: http://www.analog.com/static/imported-files/data_sheets/AD2S99.pdf ). Page 6 describes a recommended connection between AD2S99 and AD2S82A. I tried on this connection and the 16 digital outputs do not work (they just showed some erroneous outputs). I believe that other pins such as ENABLE, INHIBIT and BYTE SELECT have to be connected to something else. May I know that what is the procedure to obtain the correct 16 digital outputs (after following the recommended connection on page 6)? What are the functions of DATA LOAD and COMPLEMENT?

 

This is a 16 bit resolution application.

 

Thanks a thousand !

 

Regards

KevL
