DESCRIPTION:

The AT6538 is a high quality, high performance, low power digital output top-ported omni-directional MEMS microphone. AT6538 consists of a MEMS microphone element and an analog-to-digital converter. AT6538 has a high SNR and flat wideband frequency response with ±2dB in 12KHz. Sensitivity is a single tone distribution in a narrow window with under ±1dB, resulting in natural sound with high intelligibility. Due to built-in filter, AT6538 shows high immunity to EMI. The AT6538 is available in a thin 2.75mm ×1.85mm × 1.25mm surface-mount package. It is reflowing solder compatible with no sensitivity degradation. The AT6538 is Halogen and Lead free.
