NOTES:
5. V_SUP is the common voltage to V_{DDD and} V_DDA.
6. 550nm green LED is used in production test. The 550nm LED irradiance is calibrated to produce the same DATA count against an illuminance level
of 300 lux fluorescent light.
7. 850nm infrared LED is used in production test. The 850nm LED irradiance is calibrated to produce the same DATA_IR count against an illuminance
level of 210 lux sunlight at sea level.
8. See “Register Set” on page 10.
I²C Interface Specifications For SCL and SDA unless otherwise noted, V_{SUP(VDDD,VDDA)} = 3V, T_A = +25°C, R_EXT = 499kΩ 1%
