Isometric Views of the Microphone Package http://www.DataSheet4U.com/ GENERAL DESCRIPTION The ADMP5101 is an RF hardened, analog output, bottom-ported, omnidirectional MEMS microphone with high performance, ultralow noise, and low power. The ADMP510 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The ADMP510 sensitivity specification makes it an excellent choice for both near-field and far-field applications. The ADMP510 is pin compatible with the ADMP504 microphone. The ADMP510 has a very high signal-to-noise ratio (SNR) and extended wideband frequency response, resulting in natural sound with high intelligibility. ...
