Analog Devices ADMP801 MEMS microphone delivers 27 dBA EIN, consumes only 17 µA at 1 V supply, and is available in a 7.3 mm³ package.
Analog Devices introduced a high performance MEMS microphone developed specifically for hearing aid applications. When compared to legacy solutions like electret condenser microphones (ECMs), the ADMP801 is not only smaller in size at only 7.3 cubic millimeters, but also offers greater performance stability over temperature, time, and environmental changes, produces very low equivalent input noise (EIN) at 27 dBA SPL (sound pressure level), and consumes only 17 µA at 1V supply. The ADMP801 MEMS microphone is available in a tiny surface-mount package measuring only 3.35 mm × 2.50 mm × 0.98 mm that is reflow-solder-compatible with no sensitivity degradation.
The ADMP801 is a high quality, ultralow power, analog output, bottom-ported, omnidirectional MEMS microphone designed specifically for hearing aid applications. It is fully pick-and-place and reflow compatible, offering an option to save on cost using a mechanized assembly process as compared to ECMs that require manual assembly processes.
