Monaural Audio Class-D Amp With Power Booster For PiezoSpeaker

The AK7841 is a Monaural Class-D Amplifier for driving Piezo-Electric Speakers. Its built-in power boost DCDC converter generates adequate high voltage for driving Piezo Speaker from a Li-Ion battery. Output filter-less solution eliminates post LC-filters, which are normally required at Class-D outputs, and contributes to total space savings. Class-D operation ensures higher power efficiency. The AK7841 is the most appropriate for Cellular Phones with a piezo speaker. By AKM Semiconductor, Inc.
