Frequently Asked Question
I have limited power to supply to the part. What can I do to reduce the power consumption of the device and thus ensure that my supply is adequate?
Most power intensive features, such as the inverse sinc filter (if included on the device) can be individually powered down. If amplitude flatness across the Nyquist region is not a requirement in your application, then you could power it down to conserve power. If the comparator is not needed, powering it down will also help reduce power.
Finally, if things are really tight, you might look at the possibility of reducing the system clock frequency to the minimum necessary (say, 2.5 times the maximum output frequency). While this will reduce the power consumption, it should only be done if absolutely necessary, because oversampling usually improves the output spectral performance.
