xMEMS Announces Tomales MEMS Tweeter for Smart Glasses and Extended Reality Headset Applications

xMEMS Labs introduced Tomales, a new monolithic, 1mm-thin profile MEMS tweeter µspeaker, available with top and side-firing package options that simplify speaker placement and positioning to direct audio toward the ear in smart glasses and augmented/extended reality headset applications. This new MEMS driver, which uses the company second generation M2 speaker cell architecture, has an IP58 rating for dust/water that simplifies system integration in these designs.

xMEMS Labs confirmed that its first monolithic MEMS µspeaker, Montara, is now in production. Working closely with TSMC as its semiconductor foundry partner, the Montara design has passed all required performance and reliability qualifications and has already been selected by manufacturers for future products. The Santa Clara, California-based company confirms that the Montara was already selected for an upcoming true wireless earbuds design.

Linear Integrated Systems, a full-service manufacturer of specialty linear semiconductors, now offers the LSK 489, a 1.8-nV at 1-kHz, low-capacitance, N-channel monolithic dual JFET. The LSK 489 is part of a family of ultra-low-noise, dual JFETs specifically designed to provide users with less expensive solutions for obtaining tighter drain-source saturation current (IDSS) matching and better thermal tracking.
