The device is configured for single-shot conversion mode by setting the MODE bit to 1 in the data rate register (04h). A START command must be sent or the START/SYNC pin must be taken high for the device to start a single conversion. After the conversion completes, the device enters standby mode again. To start a new conversion, the START command must be sent again or the START/SYNC pin must be taken low and then high again.
When the device uses the sinc3 filter, ADC data requires three conversion cycles to settle. When the sinc3 filter is enabled, a single-shot conversion suppresses the first two ADC conversions and provides the third conversion as the output data so that the user receives settled data. Because three conversions are required for settled data, the conversion time in single-shot conversion mode is approximately three times the normal data period. When the device uses the low-latency filter, the ADC data settles in a single conversion. In single-shot conversion mode with the low-latency filter, the data period is closer to the normal data period.
