CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: T_J = T_C = T_A
Electrical Specifications V_DD = 3V, T_A = +25°C, R_EXT = 100kΩ, internally controlled integration timing (Note 4), unless otherwise
specified.

NOTES:
4. See Principle of Operation
5. There are three modes of the ADC’s operations. In Mode 1, the ADC integrates the current of the photodiode which is sensitive to visible and
infrared light. In Mode 2, the ADC integrates the current of the photodiode which is sensitive only to infrared light.
6. Fluorescent light is substituted by an LED at production.
7. The voltage threshold levels of the SDA and SCL pins are VDD dependent: V_TL = 0.35*V_DD. V_TH = 0.65*V_DD.
8. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
