Power consumption

I made a few measurements of the power-consumption of the SDRplay.

ADC Sample Rate: 8MHz, Zero IF , IF Bandwidth 8MHz, U=4,98V
f < 60MHz : 350mW
f > 60MHz : 550mW

When ADC Sample Rate is lowered power consumption becomes up to 100mW lower.

IF Bandwidth seems to have no influence if Sample Rate is not changed.
LNA enable/disable seems to have no influence.
