Serial Interface Communication
Times
Table 8-1 shows time/frequency of the supported
operations of the I2C serial interface for the different
serial interface operational frequencies. This, along
with the VOUT output performance (such as slew rate),
would be used to determine your application’s volatile
DAC register update rate.
