2 Specification
If not stated otherwise,
• All values are valid over the full voltage range
• Minimum/maximum values are ±3 sigma values
• Typical values of currents and state machine timings are determined at 25 °C
• Minimum/maximum values of currents are valid for the temperature range from -40°C…+85°C
• Minimum/maximum values of timings are valid for the temperature range from -40°C…+85°C
• Environmental conditions like temperature, RF, humidity are constant, unless ranges for these are specified
Pressure performance is given in Table 1, temperature performance in Table 2. If not stated otherwise:
• Parameters are valid for the range 300 – 1100 hPa @ -5 – 65 °C
• Parameters are valid before soldering after storage in standard conditions according to Table 6.
• Performance parameters are derived without MSL1 preconditioning.
• “Post-solder“ refers to 3x reflow soldering after storage in standard conditions.
