GENERAL DESCRIPTION

The ADMP4111 is a high performance, high SPL, low noise, low

power, analog output bottom ported, omnidirectional MEMS

microphone. The ADMP411 consists of a MEMS microphone

element and an impedance converter amplifier. The ADMP411

sensitivity specification makes it an excellent choice for both

near field and far field applications. The ADMP411 is pin

compatible with the ADMP401 microphone, providing an

easy upgrade path.

The ADMP411 has a linear response up to 131 dB SPL. It offers

high SNR and extended wideband frequency response resulting

in natural sound with high intelligibility. Low current consump-

tion enables long battery life for portable applications.

The ADMP411 is available in a miniature 4.72 mm × 3.76 mm

× 1.0 mm surface-mount package. It is reflow solder compatible

with no sensitivity degradation.

1 Protected by U.S. Patents 7,449,356; 7,825,484; 7,885,423; 7,961,897. Other patents are pending.
