LDC1000 wake up time

What is the wake up time to sensing after power is applied?  Datasheet says 2mS, I assume this from sleep mode.

    Hello Jaden,

    2ms is power-up time.

    Coming from the sleep mode it will take a few LC oscillation cycles to achieve stable oscillation, so the first 3 data samples may be somewhat inaccurate. After that you have stable conversion.

    Data rate is determined by the oscillation freq. and programmable Responce Time (please refer to DS)

    Hi Jaden,

    The first 3 data samples should be discarded if data is retrieved using a timer clocked to the output data rate (polling).  If data is retrieved using DRDY function on the INT pin, then sampling after the first DRDY from wakeup will be valid data.

    Thanks
