4.2 Operating conditions
All specifications are at an ambient temperature of 25°C. Extreme operating temperatures can significantly
impact specification values. Applications operating near the temperature limits should be tested to ensure
the specification.

4.3 Indicative current requirements
Table 11 lists examples of the total system supply current for a possible application.
Values in Table 11 are provided for customer information only as an example of typical power
requirements. Values are characterized on samples, actual power requirements can vary depending on
firmware version used, external circuitry, number of satellites tracked, signal strength, type of start as well
as time, duration and conditions of test.
