Stereo Audio Class-D Amp With Power Booster For Piezo Speakers

THE AK7844 is Stereo Class-D Amplifier for driving Piezo-Electric Speakers. Built-in Boost DCDC converter generates adequate high voltage for driving Piezo Speakers from Li-Ion battery. AKM state-of-the-art filter-less solution eliminates LC-filters, which are normally required at Class-D outputs. That contributes to total space saving. Class-D operation ensures higher power efficiency, and couple with Piezo Speaker that is low-power- consumption and low-profile figure. The AK7844 is very applicable for cellular phones with piezo speakers. By AKM Semiconductor, Inc.
