Sense.MIC
ProductionI2C-output MEMS microphone
The Sense.MIC pairs a Same Sky CMM-2718AT-38164W-TR analog MEMS microphone (omnidirectional, 20 Hz to 20 kHz, −38 dBV/Pa, 64 dBA SNR, 128 dB SPL overload) with an Analog Devices AD8605 amplifier and a Maxim MAX11645 12-bit ADC read over I2C (up to 1.7 MHz). The amplified microphone signal is also brought out to pad 8. Suited to sound-level monitoring and event detection: claps, knocks, voice presence, quiet versus busy.
