(1) Tested with the white LED calibrated to 2000 lux.
(2) Characterized by measuring fixed near-full-scale light levels on the higher adjacent full-scale range setting.
(3) PSRR is the percent change of the measured lux output from the current value, divided by the change in power supply voltage, as characterized by results from 3.6-V and 1.6-V power supplies.
(4) The conversion time, from start of conversion until the data are ready to be read, is the integration time plus the analog-to-digital conversion time.
(5) The specified leakage current is dominated by the production test equipment limitations. Typical values are much smaller.
