The
ADMP404
1
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.
