Omnidirectional Microphone with I2S Digital Output

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. A built-in particle filter provides high reliability.

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.
