GENERAL DESCRIPTION

The ADPD2140W is an optical sensor that detects and measures

the angle of incident infrared light within a wide field of view and

can be used in conjunction with an infrared light emitting diode

(LED) to detect user hand movements or gestures.

The ADPD2140W has an illuminated, radiant sensitive area of

ADPD2140W allows optimal integration with the ADPD1080

photometric front end. The ADPD2140W requires four

photodiode channels. Therefore it is recommended to use the

ADPD1080BCPZ with the ADPD2140W.

Packaged in a small, clear mold, 2 mm × 3 mm, 8-lead LFCSP,

the ADPD2140W is specified over the −40°C to +105°C

operating temperature range.
