The PUI Audio Microphone sensitivity of the sensor at 1 kHz and 50 cm is 0 dB equals to 1V/Pa with a range of -42 ±1 db. Its rated voltage is 2 VDC, with an operating voltage range from 1.5 to 3.6 VDC. The output impedance at 1 kHz is 300 Ω, and the current consumption is 80 μA at 2 VDC and 150 μA at 3.6 VDC. The signal-to-noise ratio at 1 kHz with a 94 dB input (A-weighted) is 59 db. The decreasing voltage from 3.6 to 1.5 VDC is 0.5 db. The frequency range is 20 to 20,000 Hz, and the total harmonic distortion at 94 dB and 50 cm 1 kHz is 0.5%. The acoustic overload point at 50 cm, 1 kHz with 10% THD is 123 db.
Max Voltage on Any Pin 4 VDC
Max Sound Pressure Level 160 dB
Max Mechanical Shock 10,000 Gs
