MEMS for real: high-fidelity microphones - ELEKTOR.com

Analog Devices has created two MEMS microphones that enable advanced audio functions for portable electronics. These functions include high-fidelity audio/video playback, hands free communication, and voice recognition with built-in wind noise suppression, and TIA-920-compliance for VoIP applications.

The ADMP 404 and ADMP405 iMEMS microphones offer SNR (signal-to-noise ratio) of 62 dB A-weighted and PSRR (power supply rejection ratio) of 70 dBV with integrated high-pass filtering. The devices are available in a 3.35 mm × 2.50 mm × 0.88 mm surface-mount package for more info...
