8.4.4 Selecting Conversion Time

The OPT4060 device offers several conversion times the user can select. Conversion Time is defined as the time to take for one measurement to complete for one channel and update the results in output register. The OPT4060 is 4-channel device, therefore the actual time to complete a 4-channel measurement is 4 times the time specified in the CONVERSION_TIME register. Measurement initiation is determined by the mode of operation as specified in Modes of Operation.
