Note) 1. Output offset voltage: VC is the reference.

2. The output voltage represents the potential variation of the output pin between the optical emission

and the dark state.

3. Items with an asterisk (*) are design confirmation items.

4. Measurement by optical input: Measurement is made by emitting light to the center of each

photodiode.

5. The load conditions (for VC) are as follows.

A to D: 2k

Ω//20pF, E+I to H+L, WPP1, WPP2: 6kΩ//20pF, RF+, RF–: (1µF + (1.3kΩ//10pF))//10pF
