AD7768-1 Reset

Category: Datasheet/Specs
Product Number: AD7768-1
Software Version: A

When in continuous mod, after power on, the converter waits for 24 CLKs to transfer the conversion result.
The exit command 0xAD, should it be placed first 0xAD0000 or last 0x0000AD ?
Or must I leave the continuous mode with 0x6C or is it 0x006C? (see page 54)
And then the 0x1D03 and 0x1D02.
The time 200 µs after RESET, is it for theese commands as well?

  • Hi  

     

    To exit continuous read mode, 0x6C should be written on the SDI.

    If CS is tied low, 16 SCLKs are needed to complete the transaction and you should write 0x006C to exit continuous read mode…

  • Hi  ,

    We will look into this. I will contact the product owner and get back to you.

    To exit continuous read mode, 0x6C should be written on the SDI.

    If CS is tied low, 16 SCLKs are needed to complete the transaction and you should write 0x006C to exit continuous read mode when using the 3-wire version of the interface.

    If you would like to exit continuous read mode and perform software reset as well, write 0xAD instead or 0x00AD if CS is tied low.

    Writing 0x1D03 then 0x1D02 is also another way to perform software reset. The 200 uS after RESET is the time required before writing to SPI.

     

    Take note that the exit command must be written between DRDY pulses to ensure that the device exits correctly.

    Thanks,
