Current consumption in power
down modes
200
nA Voltage regulator to digital part off (SLEEP state). All GDO pins
programmed to 0x2F (HW to o)
160
µA Voltage regulator to digital part on, all other modules in power
down (XOFF state)
Current consumption
1.4
mA Only voltage regulator to digital part and crystal oscillator running
(IDLE state)
7.3
mA Only the frequency synthesizer is running (FSTXON state). This
current consumption is also representative for the other
intermediate states when going from IDLE to TX, including the
calibration state.
