GENERAL DESCRIPTION
The ADMP4011 is a high quality, high performance, low power,
analog output, bottom-ported omnidirectional MEMS
microphone. The ADMP401 consists of a MEMS microphone
element, an impedance converter, and an output amplifier. The
ADMP401 sensitivity specification makes it an excellent choice
for both near field and far field applications. The ADMP401 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. The ADMP401
complies with the TIA-920 standard, Telecommunications
Telephone Terminal Equipment Transmission Requirements for
Wideband Digital Wireline Telephones.
The ADMP401 is available in a thin, 4.72 mm × 3.76 mm ×
1.0 mm surface-mount package. It is reflow solder compatible
with no sensitivity degradation. The ADMP401 is halide free.
