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 1.64 to 3.6 VDC. The current draw in full power mode is between 820 and 1000 μA, while in low power mode, it ranges from 400 to 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.
