FIGURE 2. NORMALIZED SPECTRAL RESPONSE FOR RED, GREEN AND BLUE SENSING

• 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.
• 6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
• 1. SDA and INT current sinking capability are assured by design.

• ESD Ratings
• Human Body Model (HBM)2.5kV
• Machine Model (MM) 300V
• Charged Device Model (CDM) 2kV
• Thermal Resistance (Typical)

• 6 Ld ODFN Package (Note 4)
• Maximum Junction Temperature (TJMAX)+90°C
