Target Applications

  • Smartphones and mobile phones which require HD voice quality performance
  • Multi-mic arrays and noise cancellation algorithms which benefit from microphones with tightly-matched sensitivity and phase
  • Products designed to capture super-wideband audio with little to no frequency response variation from 50Hz-14kHz
  • Small, thin consumer electronic devices using more than one microphone

Detailed Description

The AKU142 & AKU342 are fully matched top- and bottom-ported analog-output microphones in the industry standard 2.95mm x 3.76mm form factor. Designed specifically to meet the demanding requirements of mobile handset OEMs, the AKU142 & AKU342 offer excellent acoustic performance with 63dB signal-to-noise ratio (SNR) and a flat frequency response with deviations less than +5dB from 50Hz-14kHz, supporting super-wideband audio specifications. In addition, with their tight sensitivity matching of just +2dB between microphones, the AKU142 & AKU342 are ideal for use in microphone array applications where more uniform microphones lead to increased performance of noise suppression algorithms.
