GENERAL DESCRIPTION
The ADMP4041 is a high quality, high performance, 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
signal-to-noise ratio (SNR) and flat, wideband frequency response,
resulting in natural sound with high intelligibility. Its low current
consumption enables long battery life for portable applications.
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.
