DAC80501: missing information about spi command

Part Number: DAC80501
Other Parts Discussed in Thread: DAC80502,

In Datasheet/Manual sbas794e, there is no information, about the command on spi protocol.

Just bought the eval board to validate reaction with given eval software.

Saw in datasheet/manual of DAC80502 sbas793a, there is an additional Table at 8.5.1.1. Missing in document of DAC80501.

Thanks for clarication.

Stefan

    I think there are also other person, who found this issue with missing informations about spi commands, years ago.

    Document shall  be corrected.

    Hi Stefan, 

    You are correct, the table is missing. I'm marking this down in our spreadsheet for datasheet updates. 

    As you see in the DAC80502 datasheet the format is DB23 - R/W bit, DB 22-16 - register address, DB15-0 - register data. This is pretty standard for our 24 bit SPI devices which may be why the table was overlooked in the datasheet. 

    If you have any specific questions about the device, or run into more trouble, please let us know. 

    Best,
