GENERAL DESCRIPTION
The ADMP5041 is a high performance, very low noise, low
power, analog output, bottom-ported omnidirectional MEMS
microphone. The ADMP504 consists of a MEMS microphone
element, an impedance converter and an output amplifier. The
ADMP504 sensitivity specification makes it an excellent choice
for both near field and far field applications. The ADMP504 is
function- and pin-compatible with the ADMP404 microphone,
providing an easy upgrade path.
The ADMP504 has very high SNR and extended wideband
frequency response, resulting in natural sound with high

intelligibility. Low current consumption enables long battery
life for portable applications. A built-in particle filter provides
high reliability. The ADMP504 complies with the TIA-920
Telecommunications Telephone Terminal Equipment Transmis-
sion Requirements for Wideband Digital Wireline Telephones
standard.
The ADMP504 is available in an ultraminiature 3.35 mm ×
2.5 mm × 0.88 mm surface-mount package. It is reflow solder
compatible with no sensitivity degradation. The ADMP504 is
halide free.
