Alternative solutions requiring multiple sensors are, ADI asserts, often inaccurate, as the sensors “see” objects differently from varying angles making the signals difficult to combine. The single-point sensing used in the ADUX1020 optical sensor improves reliability of the application and reduces design complexity and cost for the system developer by requiring fewer components.

In addition to single-point sensing, the ADUX1020 optical sensor features high ambient light rejection, which allows reliable and accurate operation under challenging lighting conditions. This too results in a more reliable application end user experience. Other optical sensors are often challenged by ambient light from sources like full sun, high frequency LED and fluorescents, all of which can disrupt the sensor’s ability to interpret gestures accurately.

In a 2 × 3 mm, 8-lead LFCSP, the ADUX1020BCPZ costs $3.49 (1000). An evaluation kit (pictured), ADUX1020BCPZ-EVAL-SDP, is $119, with an add-on board with high power LED for longer range operation, ADUX1020BCPZ-EVALZ-LED, at $29.
