problem with the continous mode of AD7738

I cannot read the status and data registers in the continuous mode of AD7738. The single mode is OK. On page 23 of the data sheet in fig.12 the value of the mode register for the continuous mode is wrong. Couldn't find errata for the AD7738.Any idea?

  • Hi Chris,

    I think that Analog Device as a great company should release at least one Errata for the AD7738 and AD7739 to correct the

    Misleading values for the continuous mode in the pictures and in the text of the existing data sheet.

    I have one more question: do you know anyone else successfully using the continuous mode or probably

    The majority of the customers use this ADC predominantly in the single mode?

    I already sent you the scope pictures in my last e-mail and more recently I tried with 2MHZ data rate on the SPI bus.

    But nothing can make this component enter the continuous mode unfortunately.

    Best Regards,

    Peter
