For applications requiring lower throughput rates, the
user can reduce the clock frequency (f
sample rate. Figure 11 shows the typical supply current
(I
devices. The part operates in normal mode and is never
powered down. Figure 13 pertains to the 2Msps devices.

The user can also power down the ADC between con-
versions by using the power-down mode. Figure 12
shows for the 3Msps device that as the sample rate is
reduced, the device remains in the power-down state
longer and the average supply current (I
accordingly. Figure 14 pertains to the 2Msps devices.
