InvenSense's INMP411 is a high performance, high SPL, low noise, low power, analog output, bottom-ported, omnidirectional MEMS microphone. The INMP411 consists of a MEMS microphone element and an impedance converter amplifier. The INMP411 sensitivity specification makes it an excellent choice for near-field applications. The INMP411 is pin compatible with the INMP401 microphone, providing an easy upgrade path.
The INMP411 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 INMP411 is available in a 4.72 mm x 3.76 mm x 1 mm surface-mount package. It is reflow-solder compatible with no sensitivity degradation.
