Analog Devices ADMP441 iMEMS Microphone

Analog Devices announced their ADMP441 iMEMS microphone. The ADMP441 features an I2S (Inter-IC Sound) digital output, 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 ADMP441 is available in a thin 4.72 mm x 3.76 mm x 1.00 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The ADI MEMS microphone is now sampling with volume production scheduled for this June. Pricing is $2.38 per unit in 1,000-unit quantities.
