The digital microphone features a frequency range of 20 Hz to 19 kHz and utilizes Pulse Density Modulation (PDM). It is constructed using Micro-Electro-Mechanical Systems (MEMS), with the sensor element fabricated from silicon. The device operates within a supply voltage of 1.62 V to 3.6 V. Its microphone pickup pattern is omnidirectional, with a specified sound pressure level sensitivity of -36 dB ±1 dB at an SPL of 94 dB. It includes solder pads for mounting purposes.
