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 applications volatile

DAC register update rate.
