Thu, 02/17/2011 - 11:03am

LISTED UNDER:

Analog Devices introduced the ADMP441 iMEMS microphone, said to be the industry’s first high-performance MEMS microphone with an I2S (Inter-IC Sound) digital output. It also features an extended frequency response from 100 Hz to 15 kHz, high SNR (signal-to-noise ratio) of 61 dBA, and high PSRR (power-supply-rejection ratio) of 80 dBFS. The microphone uses the company’s ADI MEMS and audio signal processing technologies and is available in a thin 4.72 mm × 3.76 mm × 1.00 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The digital I²S interface with high-precision 24-bit data provides plug–and-play compatibility with industry standard digital interface for non-handset applications. It fully complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard.
