Hi BobR,
How are you writing to the part? By that I mean the sequence of the commands that you are sending to the part. Would you be able to do the following in sequence?
- Do a software reset
- Set the control registers.
- Set the offset adjust and gain adjust registers.
- Write the code to the DAC registers.
If you are going to change a setting, will you do the same sequence and check if you were able to change it successfully.
Another option is to use a spare part. This would be our last option if the part is not really functioning correctly.
Regards,
Mark
