Aid Omnidirectional MEMS Microphone

The ADMP801 is a high performance MEMS microphone with a unique combination of very low self-noise, tiny package volume (7.3 mm3), and low power consumption. Running from a 1 V supply, the ADMP801 consumes only 17 μA of current while providing an equivalent input noise of 27 dBA SPL with an analog 4.5 kΩ impedance output. These features, combined with the benefits of MEMS technology, reflow solder compatibility, and a highly stable response over time and temperature, make the ADMP801 an ideal microphone choice for assistive listening devices (ALDs) such as hearing aids.
