INMP504

Ultra-Low Noise Microphone with Bottom Port and Analog Output

GENERAL DESCRIPTION

The INMP504* is a high-performance, very low noise, low

power, analog output, bottom-ported omnidirectional MEMS

microphone. The INMP504 consists of a MEMS microphone

element, an impedance converter and an output amplifier.

The INMP504 sensitivity specification makes it an excellent

choice for both near field and far field applications. The

INMP504 is function- and pin-compatible with the INMP404

microphone, providing an easy upgrade path.

The INMP504 has very high SNR and extended wideband

frequency response, resulting in natural sound with high

intelligibility. Low current consumption enables long battery

life for portable applications. The INMP504 complies with the

TIA-920 Telecommunications Telephone Terminal Equipment

Transmission Requirements for Wideband Digital Wireline

Telephones standard.

The INMP504 is available in an miniature 3.35 mm × 2.5 mm ×

0.88 mm surface-mount package. It is reflow solder

compatible with no sensitivity degradation. The INMP504 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.
