AT6577

Overview

The AT6577 is a dual-mode MEMS microphone manufactured by Analog Technologies, Inc., designed for digital audio applications. It operates within a supply voltage range of 1.6 V to 3.6 V and features an output frequency response spanning from 100 Hz to 10 kHz. The device delivers a signal-to-noise ratio (SNR) of 64 dB(A) with a sensitivity of −26 dB FS. It utilizes Pulse Density Modulation (PDM) for data transmission and is characterized as an omnidirectional sensor. The component is constructed using silicon-based Micro-Electro-Mechanical Systems technology.
