DAC60004: Noise immunity about SPI Interface

Part Number: DAC60004

Dear Technical Support Team,

I'd like to replace from AD5024 to DAC60004.

I have been facing the command hung issue with AD5024.
AD5024 doesn't accpept the command trough SPI on the system.Output level of AD5024 keeps the last command of data andit doesn't change the output level when FPGA send command.

The only improvement is when the power is turned off

I don't know the route cause corrently, however If I replace from AD5024 to DAC60004, I hope to resolve this issue.
If you have any information about noise immunity about SPI Interface, could you share it?

Or , for example, when undefined input(such as more pulse, more clock etc) on datasheet is applied in SCLK / SDIN / SYNC ,
Does it work without hunging? If SPI hungs and DAC60004 doesn't accept command, then I hope SPI works again with POR pin or CLR pin.

I really hope to replace from AD5024 to DAC60004 to avoid command hung issue.

I think that you can't mention "No problem" , unless I find the route cause of the current problem.
but if you have any information, please give me some advice.

Best Regards,

ttd
