General Description

Halogen Free in accordance with IEC61249-2-21

The AKU142 is a surface mountable, analog output
microphone, in an industry standard 2.95 x 3.76 x
1.10mm top port package.

Target Applications

Designed

factor microphone.
Multi-mic applications

specifically

to

meet

the

demanding

requirements of mobile handset OEMs, the AKU142
offers excellent acoustic performance with 63dB signalto-noise ratio (SNR) and a flat frequency response,
with deviations less than +/-5dB from 50Hz to 14kHz,
supporting super-wideband audio specifications. In
addition, with its tight sensitivity matching of just +/-2dB
between microphones, the AKU142 is ideal for use in
microphone array applications where more uniform
microphones lead to increased performance of noise
suppression algorithms.

Smartphones and mobile phones which require HD
Voice quality acoustic performance in a small form
and

noise

cancellation

algorithms which benefit from microphones with
tightly-matched sensitivity and phase.
Products designed to capture super-wideband audio
that require a microphone with little to no frequency
response variation from 50Hz – 14 kHz.
Small, thin consumer electronic devices using more
than one microphone

Functional Block Diagram

Leveraging a unique packaging technology, the
AKU142 is the first analog MEMS microphone to match
the high SNR and flat frequency response of a bottom
port MEMS microphone, but in a convenient top port
form factor.
