Premstaetten, Austria (16 September, 2019) — ams (
The TMD2635 module from ams 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.
The earbud market is projected to enjoy compound annual growth of 27% in the years to 2023*, by which time wireless earbuds are expected to overtake all other wireless and wired product categories to become the most popular type of headphone worldwide.
Consumer audio wireless headset use continues to grow as users further immerse themselves in their modern lifestyles. By incorporating TMD2635 modules in new TWS earbud designs, wearable device manufacturers can appeal to consumers’ desire for smaller, more comfortable wearing products that are available for use for prolonged operational times because it reliably detects when

The TMD2635 module power-saving benefits are paramount especially in the small battery capacity and size of a wireless earbud product. It has an average active-mode current consumption of 70µA and 0.7µA in Sleep mode.
ams transfers deep optical sensor know-how from smartphones to wearables
The development of the TMD2635 infrared sensor module benefited from ams’ long heritage in optical sensor development and production. ams is the long-time market share leader in proximity, ambient light and color sensors and sensor modules for mobile phones. ams is a world leader in intellectual property, technologies and production capabilities for miniature optical emitters, photodetectors and spectral sensors.
The design of the TMD2635’s optical stack and the high performance of the internal laser emitter produce outstanding crosstalk rejection, high immunity to interference from ambient light, and highly effective algorithms which convert infrared light measurements to accurate proximity detection results. The proximity detection performance of the TMD2635 is comparable to that of earlier, larger modules used by the leading smartphone manufacturers, but in a significantly reduced form-factor appropriate for the small design spaces available in wearable devices.
Pricing and availability
The TMD2635 is available now in production volumes. Unit pricing is $0.89 in an order quantity of 1,000 units. For sample requests and more technical information, go to https://ams.com/tmd2635.
