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, T
AMB
=25°C
3. The accuracy of the channel counts/W/cm
2
is ±12%
4. The light source is either a 5700K white LED with an irradiance of ~600W/cm
2
, or an incandescent light with an irradiance of
~1500 W/cm
2
(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).
