NOTE: 1At ±ꢀ V input voltage and +1.0 V control voltage in darkness
2At ±ꢀ V input voltage, Averaged over any interval of 30 seconds maximum, Max pulse output signal voltage =+2 V.
3Measured at the peak quantum efficiency wavelength
4Control voltage = +1.0 V
5After 30 minutes storage in darkness
The actual output value in darkness is the sum of dark current and offset voltage.
