NOTES:
5. VSUP is the common voltage to VDDD and VDDA.
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 8.
I2C Electrical Specifications For SCL and SDA unless otherwise noted, VSUP(VDDD,VDDA) = 3V, TA = +25°C, REXT = 499kΩ 1% tolerance,
