TCS3400 − Electrical Characteristics

Figure 8:

Optical Characteristics (Clear Channel), VDD = 3V, TA = 25°C, AGAIN = 16x, ATIME = 0xF6 (27.8ms)

Note(s):

1. The white LED irradiance is supplied by a warm white light-emitting diode with a nominal color temperature of 2700K.

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

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

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

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

4. The 615 nm input irradiance is supplied by an AlInGaP light-emitting diode with the following typical characteristics: dominant

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

Figure 9:

Optical Characteristics (IR Channel), VDD = 3V, TA = 25°C, AGAIN = 16x, ATIME = 0xF6 (27.8ms)

Note(s):

1. The 850 nm input irradiance is supplied by an AlGaAs light-emitting diode with the following characteristics: peak wavelength

λP = 850 nm, spectral halfwidth Δλ½ = 42 nm.
