4.5 Current Consumption

Table 7 summarizes the steady-state current consumption for the sensor states, average current ratings

at all power terminals (VDIG, VIO, VRX, VTX), VIO 1.8 V, at Top = 25ºC. A power state defines in

what mode the sensor waits in between measurements and where DEEP_SLEEP, SLEEP and READY

states are configurable.
