P1-P3P4-P6P7-P9P10-P12P13-P14
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.
