POWER vs. THROUGHPUT RATE
The power consumption of the AD7323 varies with throughput
rate. The static power consumed by the AD7323 is very low, and
significant power savings can be achieved as the throughput
rate is reduced. Figure 49 and Figure 50 shows the power vs.
throughput rate for the AD7323 at a V
tively. Both plots clearly show that the average power consumed
by the AD7323 is greatly reduced as the sample frequency is
reduced. This is true whether a fixed SCLK value is used or if it
is scaled with the sampling frequency. Figure 49 and Figure 50
show the power consumption when operating in normal mode
for a variable SCLK that scales with the sampling frequency.
