8.1.4 Defining Power-On Timing
The low power architecture of the LDC3114 makes it possible for the device to be active all the time. When not being used, the LDC3114 can operate in Low Power Mode with a single standby power button, which typically consumes less than 10 μA. If additional power-saving is desired, or in the rare event where a power-on reset becomes necessary (see Section 7.3.8), the output data will become ready after 50-ms start-up time, about 1-ms optional register loading time, and two sampling windows for all active channels. Figure 8-5 shows the power-on timing of the LDC3114.
