ams launches the world’s smallest digital proximity sensor module. The ultra-small package of the TMD2635 occupies just 1mm3 of volume and enables audio manufacturers of True Wireless Stereo (TWS) earbud products to develop smaller, lighter industrial design earbuds. The IR proximity sensor enables wireless earbud in-and-out of ear detection to help extend battery life between chargings and can be used in tandem with another TMD2635 to enable elementary touchless gesture control without the need for buttons.

The TMD2635 module is a complete light-to-digital sensor module which integrates a low power infrared VCSEL (Vertical Cavity Surface Emitting Laser) emitter, two sensor pixels for near- and far-field sensing, and a digital fast-mode I2C interface, all in a miniature land grid array (LGA) package (more info).
