Detailed Description

The AKU250P microphone is a next-generation, HD Voice quality digital-output microphone. The AKU250P provides a high 65dB SNR, a high degree of uniformity from microphone to microphone, and low distortion, enabling the optimum performance of noise suppression algorithms and subsequent speech recognition engines. The digital-output of the AKU250P is virtually immune to all forms of radio frequency (RF) and electromagnetic (EM) interference. This allows designers the flexibility to integrate the component anywhere on the platform and obtain consistent SNR regardless of proximity to displays, Wi-Fi antennae, or other sources of interference that would otherwise degrade the signal of a conventional analog-output microphone. Additionally, the performance of the AKU250P is highly stable and therefore its high audio performance quality is maintained over the lifetime of the end-user device.

The innovative direct-port, top-port form factor of the AKU250P microphone provides the SNR and flat frequency response of a bottom-port microphone in a convenient and easy-to-use top-port package. This industry-standard form factor enables a straightforward drop-in replacement that upgrades the acoustic performance and reliability of current designs.
