NOTES: 1. Optical measurements are made using small-angle incident radiation from light-emitting diode optical sources. Visible 640 nm LEDs
ic and infrared 850 nm LEDs are used for final product testing for compatibility with high-volume production.
2. The 625 nm irradiance Ee is supplied by an AlInGaP light-emitting diode with the following characteristics: peak wavelength
λp = 625 nm and spectral halfwidth Δλ½ = 20 nm.
3. The 850 nm irradiance Ee is supplied by a light-emitting diode with the following characteristics: peak wavelength
n λp = 850 nm and spectral halfwidth Δλ½ = 42 nm.
4. The integration time Tint, is dependent on internal oscillator frequency (fosc) and on the number of integration cycles (ITIME) in the
Tech Timing Register (0xFF) as described in the Register section. For nominal fosc = 750 kHz, nominal Tint = 2.7 ms × ITIME.
