Low-noise MEMS microphone targets hearing aids
In addition, the device consumes just 17 µA with a 1-V supply, which the manufacturer reports is a fraction of the power consumed by conventional electret microphones.
The ADMP801 is an analog-output, bottom-ported omnidirectional MEMS microphone designed specifically for hearing aids. Housed in a surface-mount LGA package that is 3.35×2.50×0.98 mm, the ADMP801 is one of the smallest hearing-aid microphones on the market, and it is reflow-solderable with no sensitivity degradation.
The ADMP801 MEMS microphone costs $10.78 in lots of 1000 units. An evaluation board, the EVAL-ADMP801Z-FLEX, sells for $95 each.
