POWER CONSIDERATIONS

In the automatic power-down mode the part can be operated at

a sample rate that is considerably less than 175 kHz. In this case,

the power consumption is reduced and depends on the sample

rate. Figure 18 shows a graph of the power consumption vs.

sampling rates from 1 Hz to 100 kHz in the automatic power-

down mode. The conditions are 5 V supply at 25°C.
