SDA, SCL, INT, and ADDR to GND–0.56
Current into any pin10mA

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
Long exposure to temperatures higher than 105°C can cause package discoloration, spectral distortion, and measurement inaccuracy.

ESD Ratings

Charged-device model (CDM), per JEDEC specification JESD22-C101(2)±500
JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

All nW/cm2 units assume a 505-nm stimulus. To scale the LSB size, full-scale, and results at other wavelengths, see the Compensation for the Spectral Response section.
Characterized by measuring fixed near-full-scale light levels on the higher adjacent full-scale range setting.
Refers to a control field within the configuration register.
Tested with the white LED calibrated to 2 klux and an 850-nm LED.
PSRR is the percent change of the measured optical power output from its current value, divided by the change in power-supply voltage, as characterized by results from the 3.6-V and 1.6-V power supplies.
The conversion time, from start of conversion until data are ready to be read, is the integration time plus 3 ms.
The specified leakage current is dominated by the production test equipment limitations. Typical values are much smaller.
