INMP401

Omnidirectional Microphone with Bottom Port and Analog Output

GENERAL DESCRIPTION

The INMP401

* is a high-quality, high-performance, low-

power, analog-output bottom-ported omnidirectional MEMS

microphone. The INMP401 consists of a MEMS microphone

element, an impedance converter, and an output amplifier.

The INMP401 sensitivity specification makes it an excellent

choice for near-field applications. The INMP401 has a

wideband frequency response, resulting in natural sound with

high intelligibility. The specially designed low frequency cutoff

reduces wind noise. Its low current consumption enables long

battery life for portable applications.

The INMP401 complies with the TIA-920 Telecommunications

Telephone Terminal Equipment Transmission Requirements

for Wideband Digital Wireline Telephones standard.

The INMP401 is available in a 4.72 × 3.76 × 1.00 mm surface-

mount package. It is reflow solder compatible with no

sensitivity degradation. The INMP401 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.
