The output interface of a MEMS microphone can divide into analog and digital; moreover, analog can divide into single-ended and differential outputs. There are three different digital interfaces: PDM, I²S, and TDM. The MEMS microphone is stable, heat resistant, and can withstand reflow soldering at 260°C. The product's overall design is exceptionally tight, with a thickness of less than 1mm and a sensitivity tolerance range of +/- 1dB. Most of the applications are in mid to high-end consumer electronics products.
