The SiS3816 is a bottom port analog MEMS microphone designed in a SMD compliant package of 3.50mm x 2.65mm x 0.98mm. Integrated with reliable MEMS acoustic sensor and analog amplifier ASIC, it offers great acoustic performance with 65dB Signal-to-noise ratio (SNR), a flat wideband frequency response, and -38dBV sensitivity with ± 1dB variation range. In addition, SiS3816 operates from 1.6v to 3.6v and consumes power less than 110uA.
