Power-up time

The power-up time is the time it takes for the device to be ready to deliver an output signal after the supply voltage is applied. Depending on the device, self-tests may also be performed, configuration data loaded, or network connections established during the power-up time. For some devices, a warm-up time is specified as well as a power-up time. For these devices, the output signal should only be evaluated after the warm-up time has elapsed.
