    I need to synchronize several AD698s. Is there any option how to connect an external oscillator to AD698 or any possibility how to achieve that?

    ES,
    
 
     No.  I would build a separate oscillator and use it to drive all of the AD698s.

    Hello,
    
 
    While I know this query is regarding the AD698, please view the AD598 data sheet.  On Page 10, there is an example of how to synchronize multiple LVDT signal conditioning devices.  The excitation circuit is identical between the AD598 and the AD698.
