AD5698R READ OPERATION

Hello,

My customer is confused about AD5698R READ OPERATION.

Is it possible for you to confirm the I2C Read Operation timing?

Please find attached file. These are I2C timing chart.

As I pointed out, there are "ACK. BY Master" and the other. Compared with AD5698 and AD5698R. It seems different each other.

The customer is afraid of its typo.

Regards,

  • Hi,

    I believe this is a typo error as there is no AD5698 part. I think you are referring to either AD5696 or AD5694 which are almost identical when it comes to the digital communication.

    When writing to the part, the microcontroller acts as the master and the AD5696 is the slave. But when the read operation is being performed, this becomes reverse; the DAC is the master (because the DAC will be the one to send signals on the SDA line) and the microcontroller is the slave which receives the data being sent by the DAC.

    I believe there are no errors in the figures. They are different words but in this case, they refer to the same thing.
