Detailed Description
The AKU143 & AKU345 are fully matched top- and bottom-ported analog-output microphones in an industry standard 2.95mm x 3.76mm form factor. Designed specifically to deliver superior performance for multi-microphone noise suppression in handsets and other mobile devices, the AKU143 & AKU345 offer a high 65dB signal-to-noise ratio (SNR) and an inherently uniform sensitivity matching of just +1dB between microphones. Both microphones deliver a matched wideband frequency response with less than 5dB variations from 50Hz to 14kHz for uniform audio capture across a broad audio spectrum. The packaging of the AKU143 & AKU345 provide a high degree of RF and EM immunity, allowing for easy integration into wireless devices.
