I have purchased an ADC evaluation board, Eval Ad7621. I need technical support on how to get started in standalone mode.
When the CONTROL input of the gate array, U10, is LOW, which pulled down by default, the gate array provides the necessary signals for conversion and buffers the conversion data. Just make sure that JP22 jumper is set to INT. In parallel output mode, which is the default interface (see Table 3. S16 position 8 SER/PAR), conversion data BD[0:15] will be available at P2 (a 40-pin IDC connector) after BUSY goes HIGH.
For detailed and other configuration, here is the link for the user guide http://www.analog.com/media/en/technical-documentation/user-guides/EVAL-AD76XXEDZ.pdf
