AD7321
POWER VS. THROUGHPUT RATE
The power consumption of the AD7321 varies with throughput
rate. The static power consumed by the AD7321 is very low, and
significant power savings can be achieved as the throughput
rate is reduced. Figure 48 and Figure 49 shows the power vs.
throughput rate for the AD7321 at a V
respectively. Both plots clearly show that the average power
consumed by the AD7321 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 48 and
Figure 49 show the power consumption when operating in
normal mode for a variable SCLK that scales with the sampling
frequency.
