The acquisition phase is the time available for the input sampling capacitors to acquire a new input with the ADC running at a throughput rate of 2 MSPS.

2

A throughput rate of 2 MSPS can only be achieved with turbo mode enabled and a minimum SCK rate of 75 MHz. Refer to Table 4 for the maximum achievable

throughput for different modes of operation.

3

Transient response is the time required for the ADC to acquire a full-scale input step to ±1 LSB accuracy.

4

The minimum and maximum values are guaranteed by characterization, not production tested.

5

See the 1/f noise plot in Figure 18.
