ADPD2140 - Infrared Light Angle Sensor

Description

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.

Features

  • 2-axis light angle measurement Linear response to the angle of incident light Integrated visible light blocking optical filter No optics required and no need for precise alignment Low junction capacitance: 12.7 pF per channel at VR = 0.2 V Low reverse dark current: 1.74 pA at VR = 0.2 V (all four channels connected in parallel) 8-lead, 2 mm × 3 mm, 0.65 mm height, LFCSP.
