A miniature, low power, top port analog MEMS silicon microphone delivers excellent wideband audio performance, incorporating an acoustic sensor, low noise input buffer, and output amplifier. It achieves a -38 dBV/Pa sensitivity, a 65 dB(A) signal-to-noise ratio, and a 124 dB SPL acoustic overload point with 0.29% typical total harmonic distortion, spanning a 50 Hz to 10 kHz frequency range. Operating from a 1.5V to 3.6V supply, it draws 117 µA typically and features a 77 dB power supply rejection ratio with 400 Ohms output impedance. Encased in a 3.50mm x 2.65mm x 1.26mm LGA package, this omnidirectional component offers MaxRF Protection, ultra-stable performance, a flat frequency response, and supports standard SMD reflow across a -30°C to +100°C operating temperature range.
