Part details & applications

The ADPD2140 is an optical sensor that measures the angle of incident infrared light. Light angles calculated from the ADPD2140 response are linear to ±5° within an angular field of view of ±35°.

The ADPD2140 has a radiant sensitive area of 0.31 mm2 . The low junction capacitance and low dark current of the ADPD2140 allows optimal integration with the ADPD1080 photometric front end. The ADPD2140 can be used with a synchronous infrared light source such as a light emitting diode (LED) to detect user hand movements for gesture recognition. The ADPD2140 requires four photodiode channels. Therefore, use the ADPD1080BCPZ with the ADPD2140.

Packaged in a small, clear mold, 2 mm × 3 mm, 8-lead LFCSP, the ADPD2140 is specified over the −40°C to +85°C operating temperature range.

APPLICATIONS

Gesture for user interface control in portable devices
Object location tracking
Industrial/automation monitoring
Angle sensing
Proximity sensing
Object distance measurement (triangulation)
