Detailed Description

The AKU142 is designed specifically to meet the demanding requirements of mobile handset OEMs, & offers 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 the 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.
