Converting Photocurrent to Voltage
Vcc

Source
Iph
Vout
GND
CL
RL
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.) = Iout(max.) × RL ≦ Vout(saturation)=Vcc-0.4V
3. To avoid 60Hz ripple from fluorescent lamps, we suggest that the time constant must be
greater than 0.5 second:
RL × CL ≧ 0.5
