The ADMP504 consists of a MEMS microphone element, an impedance converter and an output amplifier.
The ADMP504 sensitivity specification makes it an excellent choice S 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 OB frequency response, resulting in natural sound with high 10140-001 ADMP504 POWER VDD GND Figure 1.
