Analog Devices has introduced its first MEMS microphone with an I2S (Inter-IC Sound) digital output.

The ADMP441 also features an extended frequency response from 100Hz to 15kHz, an SNR (signal-to-noise ratio) of 61dBA, and PSRR (power-supply-rejection ratio) of 80dBFS.

According to the supplier, the intention has been to remove the need to convert microphone output signals into standard I2S formats for non-mobile phone use.

The device is available in a 4.72 mm x 3.76 mm x 1.00 mm surface-mount package.

The ADMP441 complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard.
