4 Electrical Characteristics
1
To get better DNL results, you can sample multiple times and apply a filter, or calculate the average value.
2
kSPS means kilo samples-per-second.
4.6 Current Consumption
The current consumption measurements are taken with a 3.3 V supply at 25 °C of ambient temperature at the RF
port. All transmitters’ measurements are based on a 100% duty cycle.

1
The current consumption figures in Modem-sleep mode are for cases where the CPU is powered
on and the cache idle.
2
When Wi-Fi is enabled, the chip switches between Active and Modem-sleep modes. Therefore,
current consumption changes accordingly.
3
In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on
the CPU load and the peripherals used.
4
In practice, the power consumption might be different depending on which peripherals are en-
abled.
