1. 565nm Green, 620nm Red LED, 485nm Blue in white LED is used in production test. Its irradiance is calibrated to produce the same DATA count against an illuminance level of 130 lux fluorescent light.

2. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

3. SDA and INT current sinking capability are assured by design.

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.
