Detailed Description

The AKU151 is a small, top port, analog-output MEMS microphone. The microphone consists of a MEMS acoustic sensor and an integrated circuit (IC) with a pre-amplifier, charge pump, and supporting circuitry, all in a small footprint package measuring 3.42mm x 1.70mm x 0.93mm.

Designed specifically to provide high acoustic performance in a tiny top-port footprint, the AKU151 is ideal for space- constrained, wearable accessories, Internet of Things (IoT) nodes, and smartphones that require excellent acoustic performance. The AKU151 offers 65dB signal-to-noise ratio (SNR) and uniform sensitivity matching of just +/-1dB between microphones.

The metal lid package is immune to RF and Electromagnetic (EM) interferences, allowing for easy integration into wireless devices.
