I have been looking at specs for A/D converters trying to find the perfect candidate (8 bits parallel out, 8 MSPS minimum, low power consumption).
It appears that most of the data sheets specify power consumption at the highest-rated conversion frequency. Am I correct in my belief that there is a significant savings in power if the converter is run slower than that?
For example, the Analog Devices AD9280 meets my requirements, but the
95 mW power consumption would make it the hottest component on my board. If I run it at 4 MSPS instead of the rated 32 MSPS, how much power consumption difference should I see?
