digital conversions performed on them sequentially with the supply voltage VCC acting as the voltage reference for
the ADC.
After each conversion is performed, the device places itself into power-down mode. Upon a read command, the
device will wake itself up and prepare for a conversion, which takes approximately 0.6 μs. The actual conversion
process takes approximately 1.0 μs.
