Output Specifications
| Parameter | Symbol | MIn. | Typ | Max | Unit | Condition |
|---|---|---|---|---|---|---|
| Output Current | I_OUT1 | 6.3 | 19 | 31 | uA | Vcc=3V, Lux= 10(Illuminance by CIE standard light source) |
| Output Current | I_OUT2 | 90 | 230 | 370 | uA | Vcc=3V, Lux= 100(Flourescent light is used as light source) |
| Output Current | I_OUT3 | - | 276 | - | uA | Vcc=3V, Lux= 100(White LED is used as light source) |
| Dark Current | I_DARK | - | 50 | 160 | nA | Vcc=3V, Lux= 0 |
Sensitivity(Light current ratio) | I_OUT3/I_OUT2 | - | 1.2 | - | - | - |
| Rise Time | Tr | - | 0.95 | 2 | ms | Vcc=3.0V,Lux=100,Rload=1k(White LED is used as light source) |
| Fall Time | Tf | - | 0.8 | 2 | ms | Vcc=3.0V,Lux=100,Rload=1k(White LED is used as light source) |
| Supply Current | Icc | - | 2.5 | - | mA | Vcc=3.0V,Lux=100,Rload=1k(White LED is used as light source) |
| Saturated Output Voltage | Vo | 2.2 | 2.32 | - | V | Vcc=3.0V,Lux=100,Rload=1M(White LED is used as light source) |
| Peak Sensitivity Wavelength | - | 620 | - | nm | ||
| Propagation Delay time | td | - | 600 | - | us | Vcc=3.0V,Lux=100,Rload=1k(White LED is used as light source) |
| Storage Delay time | ts | - | 200 | - | us | Vcc=3.0V,Lux=100,Rload=1k(White LED is used as light source) |
So if we check the figure and the sensitivity the change in wavelength changes the sensitivity response. The change in Lux also changes the current by 1.2.
