DAC5672A: Can both output channel change at exact same time when use in Interleave mode?

[FAE] Andrew Wang

Part Number: DAC5672A

Hi Team,

Customer is asking if DAC5672A CH1 and CH2 can output at same phase (no delay between each other) and same voltage when use in the interleave mode?

If not exact the same phase, can we expect what is worst case time difference and any walk-around to make both output same phase?

Timing alignment is very critical thing to customer's application.

Thanks!!

Hi Andrew,

Yes the CH1 and CH2 outputs should have same phase when used in interleaved single bus mode. The customer have to make sure to follow all the timing requirements as shown page 15 figure 20 of the datasheet.
