INMP510

RF-Hardened, Ultra-Low Noise Microphone with Bottom Port and Analog Output

GENERAL DESCRIPTION

omnidirectional MEMS microphone with high performance,

ultra-low noise, and low power. The INMP510 consists of a

MEMS microphone element, an impedance converter, and an

output amplifier. The INMP510 sensitivity specification makes

it an excellent choice for both near-field and far-field

applications. The INMP510 is pin compatible with the INMP504

microphone. The INMP510 has a very high signal-to-noise

ratio (SNR) and extended wideband frequency response,

resulting in natural sound with high intelligibility. Low current

consumption enables long battery life for portable

applications.

The INMP510 is available in a miniature 3.35 × 2.5 × 0.98 mm

surface-mount package. It is reflow solder compatible with no

sensitivity degradation.

*Protected by U.S. Patents 7,449,356; 7,825,484; 7,885,423; and 7,961,897.

Other patents are pending.
