DAC8580: DAC8580IPW. Broken Device . Output-pin wave is incorrect.

Hi,

Can you please clarify the following:

1. Is the error transient at device startup, or are you writing to the device?

2. Can you provide a screenshot of the communication to the device that results in the error transient?

3. Can you monitor the reference voltage as the error transient occurs?

4. Does the device recover after the transient? Can additional inputs be provided to the device? 

5. Are all the digital input pins stable during the transient? For example, does the value of OSR1, OSR2, RESTB, BPB, and MUTEB change before or during the transient?

Thanks,

Paul
