GRAS Sound & Vibration Announces New 1/2” CCP Low-noise Microphone

GRAS Sound & Vibration introduced a new, 1/2” CCP low-noise microphone that is particularly well suited for the consumer electronics industry. GRAS offers an extensive line of low-noise microphones for measuring low noise in confined spaces, or environments with a low noise floor. Now, the world-renowned manufacturer of high quality measurement microphones and related acoustic sensors, confirmed the availability of the 47HC model that is particularly well suited for use in the automotive NVH and consumer electronics industries.

Here’s something close to our hearts. This project from our own technical editor and renowned publisher of the famous Linear Audio bookzine collection, Jan Didden, is now campaigning on Kickstarter. With audio projects steadily getting smaller, the SilentSwitcher is an ideal low-noise +/-15V & 5V power supply board for mixed analog/digital projects with no audible noise, no mains hum, no RFI and minimal heat.

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.
