GENERAL DESCRIPTION
The ADMP404 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.
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.
