TCS3471 − Absolute Maximum Ratings

Figure 7:

Operating Characteristics; VDD = 3 V, TA = 25ºC (unless otherwise noted)

Figure 8:

Optical Characteristics; VDD = 3 V, TA = 25ºC, GAIN = 16, ATIME = 0xF6 (unless otherwise noted)

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

dominant wavelength

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

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

dominant wavelength

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

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

dominant wavelength

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