Stereo Audio Class-D Amp With Power Booster For Piezo SpeakersTHE 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.
