The AT6856 is a high quality, low cost, low power analog output bottom-ported omni-directional MEMS microphone. AT6856 consists of a MEMS microphone element and an preamplifier. AT6856 has a high SNR and flat wideband frequency response, resulting in natural sound with high intelligibility. Extra EMI filter for RF noise attenuation is built inside. Due to the built-in filter, AT6856 shows high immunity to EMI. The AT6856 is available in a thin 2.75mm × 1.85mm × 0.9mm surface-mount package. It is reflowing solder compatible with no sensitivity degradation. The AT6856 is Halogen and Lead free.
