I am just studing to use your AD7985 with your datasheet page.19, Fig 27 CSB Mode, 3-Wire Without Busy Indicator Serial Interface Timing (SDI High) condition. Also I will be worked AD7985 with fix the procedure of conversion and acquition.
When there is no input signal after power on, can I put SCK to AD7985 when convert? Or not?
When I pause the convert operation during acquition,,,
Should I read the paused-data again, if I would like to start the convert operation.
Thank you for choosing our product in your application. Yes, you can put SCK even if there is no input signal. What you should avoid is having an input signal if the part is not powered up. As for the second question, you do not need to read the data in order to start a new conversion.
If you have more queries, it would help if you share more information on how you intend to use our product in our system.
Hope this helps.
Thank you Karen.
I can proceed this study to forward.
