INMP404

Omnidirectional Microphone with Bottom Port and Analog Output

GENERAL DESCRIPTION

The INMP404* is a high-quality, high-performance, low-

power, analog-output bottom-ported omnidirectional MEMS

microphone. The INMP404 consists of a MEMS microphone

element, an impedance converter, and an output amplifier.

The INMP404 sensitivity specification makes it an excellent

choice for near-field applications. The INMP404 has a

wideband frequency response, resulting in natural sound with

high intelligibility. Its low current consumption enables long

battery life for portable applications.

The INMP404 complies with the TIA-920 Telecommunications

Telephone Terminal Equipment Transmission Requirements

for Wideband Digital Wireline Telephones standard.

The INMP404 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 INMP404 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.
