AD7329
POWER VS. THROUGHPUT RATE
The power consumption of the AD7329 varies with throughput
rate. The static power consumed by the AD7329 is very low, and
significant power savings can be achieved as the throughput
rate is reduced. Figure 55 and Figure 56 shows the power vs.
throughput rate for the AD7329 at a V
respectively. Both plots clearly show that the average power
consumed by the AD7329 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 55 and
Figure 56 show the power consumption when operating in
normal mode for a fixed 20 MHz SCLK and a variable SCLK
that scales with the sampling frequency.
