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.
NOTE:
4. _JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
Electrical Specifications V_DD = 3V, T_A = +25°C, R_EXT = 499kΩ 1% tolerance, 16-bit ADC operation, unless otherwise specified.

NOTES:
5. 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.
6. 850nm IR 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.
7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
