GENERAL DESCRIPTION
The ADMP405 is a high quality, high performance, low power,
analog output, bottom-ported omnidirectional MEMS
microphone. The ADMP405 consists of a MEMS microphone
element, an impedance converter, and an output amplifier. The
ADMP405 sensitivity specification makes it an excellent choice
for both near field and far field applications. The ADMP405 has
a high SNR and flat wideband frequency response, resulting in
natural sound with high intelligibility. The specially designed
low frequency cutoff reduces wind noise. Low current
consumption enables long battery life for portable applications.
A built-in particle filter provides high reliability. The ADMP405
complies with the TIA-920 Telecommunications Telephone
Terminal Equipment Transmission Requirements for Wideband
Digital Wireline Telephones standard.
The ADMP405 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 ADMP405 is
halide free.
