MICROPHONES – MEMS
SiSonic
The SiSonic
shipments exceeding 400 million units to date. The proven and evolving design series continues to
support high-performance, high-density innovation in such applications as cell phones, digital still
cameras, portable music players, premium earbuds and other portable electronic devices.
Design variables include ever-smaller sizes, lower profiles and mounting options, increased output
capacities, and new digital audio options that eliminate analog noise. For manufacturers, surface
mount designs eliminate off-line subassembly production costs. Customized designs are supplied on
tape-and-reel and can be run through standard automatic pick-n-place equipment during in-line
surface mount manufacturing.
The microphones can also be integrated with our patented IntelliSonic
a precisely customized sound.

Part Numbering
Ultrasonic Acoustic Sensor
Derived from our industry-leading MEMS silicon surface mount microphone technology,
our new ultrasonic sensor designs function on a high frequency band. Sensor designs
are possible across a wide spectrum of applications requiring highly miniaturized
solutions for sensing and actuation/signaling.
New digital mics eliminate analog noise
New integrated designs with differential or switchable gain
Zero Height Mic
Original "mini" with footprint less than 18mm
RF Hardened products eliminate GSM/TDMA burst noise
in handset designs
