Analog Devices has sold its MEMS Microphone product line to InvenSense.
Please visit the InvenSense ADMP411 product page for all technical support and sales information.
The ADMP411 is a high performance, high SPL, low noise, low power, analog output bottom-ported, omnidirectional MEMS microphone. The ADMP411 consists of a MEMS microphone element and an impedance converter amplifier. The ADMP411 sensitivity specification makes it an excellent choice for both near field and far field applications. The ADMP411 is pin-compatible with the ADMP401 microphone, providing an easy upgrade path.
The ADMP411 has a linear response up to 131 dB SPL. It offers high SNR and extended wideband frequency response resulting in natural sound with high intelligibility. Low current consumption enables long battery life for portable applications.
The ADMP411 is available in a miniature 4.72 mm × 3.76 mm × 1.0 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
