UltraLow Noise Microphone with Bottom Port and Analog Output
Please visit the InvenSense ADMP504 product page for all technical support and sales information.
The ADMP504 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. 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.
