Tiny Akustica 1mm x 1mm MEMS Microphone Is Now Digital
AKU2002C Debuts as Company's Next-Generation Digital MEMS Microphone

PITTSBURGH, PA--(Marketwire - November 10, 2008) - Akustica, Inc., maker of award-winning
Complementary Metal Oxide Semiconductor (CMOS) microelectromechanical
systems (MEMS) microphones, today introduced its latest generation of
digital microphones that greatly improves voice quality in notebook
computers and other consumer-electronic devices. The new AKU2002C is the
first digital microphone product from Akustica to leverage its new 1mm x
1mm monolithic digital-output microphone.
Earlier this year, Akustica introduced the world's smallest analog
microphone, the AKU1126, a fully integrated 1mm x 1mm analog microphone die
in a compact 2mm x 2mm package. This and all other products in Akustica's
portfolio are manufactured using Akustica's patented and revolutionary CMOS
MEMS technology, in which both the transducer and the electronics are
fabricated in a single chip, in a CMOS wafer, using standard CMOS
processes.
"Laptop manufacturers recognize the improvement in voice quality that can
be achieved using digital microphones and are adopting them rapidly," said
Davin Yuknis, vice president of marketing and product management for
Akustica. "Because our CMOS MEMS technology allows us to quickly innovate
and introduce new digital microphones such as the AKU2002C, we provide
manufacturers with features and form factors they need now to move forward
with next-generation laptop designs."
About the AKU2002C
The AKU2002C is an omni-directional, digital-output, CMOS MEMS microphone
in a 3.76mm x 4.72mm industry-standard package. It is pin- and
footprint-compatible with earlier generations of the AKU2002. The AKU2002C
is
lead-free, surface-mountable, RoHS compliant, and automated
pick-and-place-compatible for improved manufacturing reliability and
efficiency.
The output of the AKU2002C is pulse density modulated -- a single-bit
digital output stream that can be decimated by a digital filter in
downstream electronics for a high degree of design flexibility. The output
of two AKU2002C microphones can be multiplexed for stereo microphone
functionality on only one data wire. The robust digital output of the
microphone provides a high degree of immunity to RF (Radio Frequency) and
EM (Electromagnetic) interference on the audio path, a problem which is
costly and difficult to overcome when placing a traditional analog output
microphone into the bezel of a laptop monitor. The AKU2002C provides as
good or better PSR (Power Supply Rejection) and SNR (Signal to Noise Ratio)
as previous generations of Akustica digital microphones as well as other
digital MEMS microphones in production today.
Price and Availability
The AKU2002C is currently in limited production and will be in full
production in Q109. The AKU2002C is $2.09 in 1000 unit quantities. For
