The SiS3817 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, SiS3817 operates from 1.4v to 3.6v and consumes power less than 110uA.
