DAC43401-Q1: No oscilaltion in all gain condition?

Takahiro Saito

Part Number: DAC43401-Q1
Other Parts Discussed in Thread: DAC43401

Hi team,

Customer want to make sure if DAC43401 will not oscillate in all gain condition.

If customer keep capacitive load less than 1nF (RL=Infinite) and 2nF (RL=5kohm), there is no risk of the oscillation, right?

If any phase compensation are needed in response to the gain setting, could please advise me how to do that?

Hi Saito-san,

I do no think there is any risk, but I would like to double check with the design team. Please allow a few days for their response.

Hi Saito-san,

I heard back about this question. With OUT and FB connected, there is no risk of oscillation for any of the gain settings as long as the cap is below the 1nF (RL=Infinite) or 2nF (RL=5kohm) limit.
