AS7263 − Timing Characteristics

Optical Characteristics

Figure 12:

Optical Characteristics of AS7263 (Pass Band)(1)

Note(s):

1. Calibration & 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 an incandescent light with an irradiance of ~1500μW/cm2 (300-1000nm). The energy at each channel (R, S, T, U,

V, W) is calculated with a ±33nm bandwidth around the center wavelengths (610, 680, 730, 760, 810, 860nm).
