PUI Audio Microphone MEMS, 18 kHz

The PUI Audio Microphone features omnidirectional directivity with a sensitivity of 0 dB equals to 1V/Pa at 1 kHz and 50 cm from a 94 dB source, rated at -26 ± 1 db. It uses a 1/2 Cycle PDM data format and operates at a rated voltage of 1.8 VDC, with an operating voltage range of 1.5 to 3.6 VDC. The current draw in full power mode ranges from 820 to 1000 μA, and in low power mode, it is between 400 and 450 μA. The signal-to-noise ratio at 1 kHz with a 94 dB input (A-weighted) is 63 dB in full power mode and 61 dB in low power mode. The frequency range spans from 20 to 18,000 Hz.
