TCS3772 − Electrical Characteristics

Figure 8:

Optical Characteristics, VDD = 3 V, TA = 25°C, AGAIN = 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 465 nm input irradiance is supplied by an

InGaN light-emitting diode with the following characteristics: dominant wavelength

λD=465nm, spectral halfwidth Δλ½ = 22 nm.

3. The 525 nm input irradiance is supplied by an

InGaN light-emitting diode with the following characteristics: dominant wavelength

λD=525nm, spectral halfwidth Δλ½ = 35 nm.

4. The 615 nm input irradiance is supplied by a Al

InGaP light-emitting diode with the following characteristics: dominant wavelength

λD=615nm, spectral halfwidth Δλ½ = 15 nm.
