Converting Photocurrent to Voltage
Vcc
Current
Amp
I ph
Vout
R L
C L
GND
Note:
1. The output voltage (V out ) is the product of photocurrent (I PH ) and loading resistor (R L )
2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light,
and output saturation voltage:
V out (max.) = I out (max.) × R L ≦ V out (saturation) ＝ V cc － 0.8V
3. To avoid 60Hz ripple from fluorescent lamps, we suggest that the time constant must be
greater than 0.5 second:
R L × C L ≧ 0.5
