PRELIMINARY DATA

P H O T O I C

Photo IC for rangefinder

S8040

S8040 is a light modulation photo IC consisting of a dual photodiode and a control/processing circuit integrated on a single chip. When used with

an infrared LED and light emitting/receiving lenses, S8040 detects the distance (near or far) to an object based on a prespecified distance by

utilizing the triangular distance measurement method. S8040 can be operated in 2 modes: self-running mode and single trigger mode. Current

consumption during standby (no distance detection) is held to 20 µA Max. Average current consumption is minimized by setting a longer

measurement cycle.

Self-running mode: Operates with a measurement cycle proportional to the external capacitor value. (250 ms Typ. at 0.1 µF)

Single trigger mode: Detects the distance only when a trigger pulse is input to the TRIG terminal.
