(1) Characterized by measuring fixed near-full-scale light levels on the higher adjacent full-scale range setting.
(2) Refers to a control field within the configuration register.
(3) Tested with the white LED calibrated to 2k lux and an 850-nm source.
(4) PSRR is the percent change of the measured lux output from its current value, divided by the change in power supply voltage, as characterized by results from 3.6-V and 1.6-V power supplies.
(5) The conversion time, from start of conversion until the data are ready to be read, is the integration time plus 3 ms.
(6) The specified leakage current is dominated by the production test equipment limitations. Typical values are much smaller.
