Hi Chen,
Thank you for your query. The settling time of DAC081C081 is 4.5us max and the I2C frame length will be < 35us at 1MHz clock frequency. This will give an I2C update rate a bit higher than 25kHz. But the problem is that getting a 1MHz clock frequency in I2C can be a challenge if there are multiple devices on the bus. It is a good idea to go for an SPI device for your requirement. For example, you can use DAC081S101.
But if you want a short answer, it is possible to get 25kHz output from this part.
Hope that answers your question.
