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.) = Iout(max.) × RL ≦ Vout(saturation)＝Vcc－0.8V 3. To avoid 60Hz ripple from fluorescent lights, suggest that time constant must be greater than 0.5second： RL x CL > 0.5 (empirical data) Everlight Electronics Co., Ltd.
