INMP441

Omnidirectional Microphone with Bottom Port and I2S Digital Output

GENERAL DESCRIPTION

The INMP441 is a high-performance, low power, digital-output,

omnidirectional MEMS microphone with a bottom port. The

complete INMP441 solution consists of a MEMS sensor, signal

conditioning, an analog-to-digital converter, anti-aliasing filters,

power management, and an industry-standard 24-bit I²S interface.

The I²S interface allows the INMP441 to connect directly to digital

processors, such as DSPs and microcontrollers, without the need

for an audio codec in the system.

The INMP441 has a high SNR, making it an excellent choice for

near field applications. The INMP441 has a flat wideband

frequency response, resulting in natural sound with high

intelligibility.

The INMP441 is available in a thin 4.72 × 3.76 × 1 mm surface-

mount package. It is reflow- solder compatible with no sensitivity

degradation. The INMP441 is halide free.

*Protected by U.S. Patents 7,449,356; 7,825,484; 7,885,423; and 7,961,897.

Other patents are pending.
