8.4.6 Light Resolution

The OPT4001 device's effective resolution is dependent on both the conversion time setting and the full-scale light range. Although the LSB resolution of the linear ADC_CODES doesn’t change, the effective or useful resolution of the device is dependent on the conversion time setting and the full-scale range as per the table below. In conversion times where the effective resolution is lower, the LSBs are padded with 0.
