Hello,

I would like to ask about AD779x conversion time.

What is effect to conversion time variation? If internal clock variation on AD779x product to product, do you have any information about internal clock variation product to product?


For example,  AD779x as single conversion mode, 16.6Hz update rate, 1/4 clock ratio.

At this case, we can estimate AD conversion time as 482ms (1/16.6x2x4). But in fact it takes 492ms on target board (over 10ms than estimation).

 

Thank you for your help in advance.

Best regards,

Sofy
