The power consumption during normal operation is listed here. The actual cosumption may vary depending on MCE firmware parameter settings, etc.
This is calculated based on Vcore = 3V, Vlvd=4.5V, Va+=6.2V, Va− = −6.2V, Vah=10V.

1 In Rev. F1, in order to save power, L12 and L13 (ECO-055) are removed to disable regulators U34 and U35 supplying +/-5V to the low noise bias channels. This results in total of ~2.7W power saving.
