T C S3771 − Electrical Characteristics

Figure 8:

Optical Characteristics, VDD = 3V, TA = 25°C, Gain = 16, ATIME = 0xF6 (unless otherwise noted)

(1)

Note(s):

1. The percentage shown represents the ratio of the respective red, green, or blue channel value to the clear channel value.

2. The 465nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics:

dominant wavelength λD = 465nm, spectral halfwidth Δλ½ = 22nm, and luminous efficacy = 75lm/W.

3. The 525nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics:

dominant wavelength λD = 525nm, spectral halfwidth Δλ½ = 35nm, and luminous efficacy = 520lm/W.

4. The 625nm input irradiance is supplied by a AlInGaP light-emitting diode with the following characteristics:

dominant wavelength λD = 625nm, spectral halfwidth Δλ½ = 9nm, and luminous efficacy = 155lm/W.
