CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
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 1%, I²C command = 00(hex) (Note 1), unless otherwise specified.

NOTES:
1. For I²C command = 00H, the ADC converts the current of (photo) diode 1 into a 16 bit data with an internally timed integration of 110ms for
R_EXT = 100kΩ, 1% tolerance.
2. Minimum I²C Clock Rate is guaranteed by design.
3. Fluorescent light is substituted by an LED at production.
4. 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.
