GENERAL DESCRIPTION
The ADMP404 is a high quality, low cost, low power, analog
output bottom-ported omnidirectional MEMS microphone.
The ADMP404 consists of a MEMS microphone element, an
impedance converter, and an output amplifier. The ADMP404
sensitivity specification makes it an excellent choice for both
near field and far field applications. The ADMP404 has a high
SNR and flat, wideband frequency response, resulting in natural
sound with high intelligibility. Low current consumption
enables long battery life for portable applications. A built-in
particle filter provides high reliability. The ADMP404 complies
with the TIA-920 Telecommunications Telephone Terminal
Equipment Transmission Requirements for Wideband Digital
Wireline Telephones standard.
The ADMP404 is available in an ultraminiature 3.35 mm ×
2.50 mm × 0.88 mm surface-mount package. It is reflow solder
compatible with no sensitivity degradation. The ADMP404 is
halide free.
