I'm using an AD5292 digital potentiometer to change some voltage and an LTC2400 on the same SPI interface. However, my SDO is stuck to ground as a result of the AD5292 and the LTC2400 is not able to pull it high.

I assume that if the supply voltages are taken down (VSS, VDD, VLOGIC), at some point the analog switches will become open and the terminals A, B and W will be open circuit.
Unfortunately, the datasheet does not give a value for that, like a brownout…
Hi,
I also was hoping to find more information on the segmented RDAC architecture.

Hi, I'm working on a project with CI AD5292 and I wonder to know
Hello engineers!
I'm having trouble with my prototype and try to investigate every possible problem.
I have an Audio Clipping circuit in my analog audioprocessor design. I am using the AD5292 100k digipot for this purpose. In the image below you see…
I have 3 SPI buses with AD5292 DPOTS on each of them and only one those buses is daisy chained with 6 AD5292 DPots (TX only). The 2 the other AD5292 devices on the SPI buses can be controlled with no issues. The daisy chain bus doesn't respond to commands…
I have a follow-up question regarding this issue:
If the supply voltages are taken down (VSS, VDD, VLOGIC), at some point the analog switches will become open and the terminals A, B and W will be open circuit.
