Omnidirectional Microphone with Bottom Port and IS Digital Output

Analog Devices has sold its MEMS Microphone product line to InvenSense.

Please visit the InvenSense ADMP441 product page for all technical support and sales information.

The ADMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with a bottom port. The complete ADMP441 solution consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, antialiasing filters, power management, and an industry standard 24-bit I2S inter-face. The I2S interface allows the ADMP441 to connect directly to digital processors, such as DSPs and microcontrollers, with-out the need for an audio codec in the system.

The ADMP441 has a high SNR and high sensitivity, making it an excellent choice for far field applications. The ADMP441 has a flat wideband frequency response, resulting in natural sound with high intelligibility.

The ADMP441 is available in a thin 4.72 mm × 3.76 mm × 1 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The ADMP441 is halide free.
