DAC81408: DAC81408 Streaming mode

Yuta Nishie

Part Number: DAC81408

Hi,

I am considering using Streaming mode to update registers 14h to 1Bh.

Which is shorter, the data update wait time using LDAC or the data update wait time in Streaming mode?

When using LDAC, I recognize that TDACWAIT is required for the update wait time, while in Streaming mode, I recognize that there is no update wait time.

Best Regards,

Hi Nishie,

As the name suggests, its for the sequential DAC update wait time. In streaming mode, you are going to update all the data registers after LDAC goes low if you are using LDAC to update the same. Alternatively you can use asynchronous mode as well.

in both case you need to wait min 1uS before you send the next data update command ( I mean after updating all 8 data registers).

Yes, streaming mode is faster than individual DAC channel update.
