                    Same Sky’s analog and digital MEMS microphones deliver enhanced audio quality in extremely compact packages
    

Image of Same Sky's MEMS Microphones Same Sky's MEMS microphones provide users with improved audio quality and performance in compact, low-profile packages as small as 2.75 mm x 1.85 mm x 0.90 mm. Featuring sensitivity ratings from -42 dB up to -26 dB, signal-to-noise ratios from 57 dBA up to 65 dBA, and sensitivity tolerances as low as ±1 dB, these MEMS microphones are ideal for a range of portable consumer electronics applications.

For easier prototyping and design testing, Same Sky also offers a MEMS microphone development kit consisting of four independent microphone evaluation circuits. (Please see below for more kit information)
