ADMP401:  IMEMS® MICROPHONE OMNI DIRECTIONAL MICROPHONE WITH BOTTOM PORT AND ANALOG OUTPUT

The ADMP401 is a high quality, low cost, low power, analog output bottom ported omni-directional MEMS microphone. The ADMP401 has a high SNR of 62dBA, and a very high sensitivity at -42 dBV. The high SNR and sensitivity make the ADMP401 excellent for near field and far field applications. The ADMP401 has a flat frequency response from 100 Hz to15 kHz suitable for wideband audio applications. Low ...More

ADMP401:  IMEMS® MICROPHONE OMNI DIRECTIONAL MICROPHONE WITH BOTTOM PORT AND ANALOG OUTPUT

Product Description

The ADMP401 is a high quality, low cost, low power, analog output bottom ported omni-directional MEMS microphone. The ADMP401 has a high SNR of 62dBA, and a very high sensitivity at -42 dBV. The high SNR and sensitivity make the ADMP401 excellent for near field and far field applications. The ADMP401 has a flat frequency response from 100 Hz to15 kHz suitable for wideband audio applications. Low current consumption enables long battery life for portable applications. A built in particle filter provides for high reliability.

The ADMP401 is available in very thin 4.72 mm × 3.76 mm × 1.00 mm surface mount package. It is surface mount reflow solder compatible with no sensitivity degradation.
