Figure 6:
Electrical Characteristics
Note(s):
1. The supply voltage V
DD
is sampled during boot and should not vary during operation.
2. The maximum V
DD
ramp time for Power On is 3ms.
3. Typical values for 1.8V supply voltage (V
DD
).
4. Average Supply Current (I
DD
) for a sensor measurement once every 60 seconds.
5. For SDA and SCL timing refer NXP I²C – bus specification and user manual UM10204.
6. Typical values at 25
o
C and 50% RH.
