GND
Note:
1. The output voltage (Vout) is the product of photocurrent (IPH) and loading resistor (RL)
2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light,
and output saturation voltage:
Vout(max.) = IPH(max.) × RL Ù Vout(saturation)ØVccÑ0.4V
RL × CL Ú 0.5 (empirical data)
