INMP405

Omnidirectional Microphone with Bottom Port and Analog Output

GENERAL DESCRIPTION

The INMP405* is a high-quality, high-performance, low-power,

analog-output bottom-ported omnidirectional MEMS

microphone. The INMP405 consists of a MEMS microphone

element, an impedance converter, and an output amplifier.

The INMP405 sensitivity specification makes it an excellent

choice for near-field applications. The INMP405 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 INMP405 complies with the TIA-920 Telecommunications

Telephone Terminal Equipment Transmission Requirements for

Wideband Digital Wireline Telephones standard.

The INMP405 is available in a miniature 3.35 ×

2.50 × 0.88 mm surface-mount package. It is reflow solder

compatible with no sensitivity degradation. The INMP405 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.
