S4282-51, S6809, S6846, S6986 and S7136/-10 Series Photo ICs
This family of light modulation ICs, from Hamamatsu, were developed for optical synchronous detections under disturbance background light. A monolithic photo IC chip contains a photodiode, preamplifier, comparator, oscillator, LED driver and signal processing circuit etc. Suitable applications include paper detection in office machines and optical switches.
Features of the light modulation photo ICs: Large allowable background light level Minimum detection level Digital output Small plastic package Small hysteresis (S6809)
