This microphone is digital and uses a PDM (Pulse Density Modulation) technique with MEMS (Micro-Electro-Mechanical Systems) technology based on silicon. Its operating voltage range spans from 1.62 volts to 3.6 volts. Additionally, the microphone features noise cancellation capabilities, boasting a noise reduction of -36 decibels ±1 decibel at an SPL (Sound Pressure Level) of 94 decibels. It also has solder pads for connectivity.
