AS7262 − Optical Characteristics

Figure 12:

Optical Characteristics of AS7262 (Pass Band) (1)

Note(s):

1. Calibration and measurements are made using diffused light

2. Each channel is tested with GAIN = 16x, Integration Time (INT_T) = 166ms and VDD = VDD1 = VDD2 = 3.3V, TAMB=25°C

3. The accuracy of the channel counts/μW/cm2 is ±12%

4. The light source is either a 5700K white LED with an irradiance of ~600μW/cm2, or an incandescent light with an irradiance of

~1500 μW/cm2 (300-1000nm). The energy at each channel (V, B, G, Y, O, R) is calculated with a ±40nm bandwidth around the center

wavelengths (450nm, 500nm, 550nm, 570nm, 600nm, 650nm).
