NJU8761 www.DataSheet4U.com PRELIMINARY Analog Signal Input Monaural Class-D Power Amplifier for Piezo Speaker GENERAL DESCRIPTION The NJU8761 is an analog signal input monaural class-D amplifier for Piezo speaker. The NJU8761 incorporates BTL amplifiers, which eliminate AC coupling capacitor. The input block operates on 2.6V(Min.) as power supply and the output block operates up to 12V, therefore it can output close to 17.5VP-P amplified signal and drive Piezo speaker with louder sound and high efficiency. Class-D operation achieves lower power operation for Piezo speaker, thus the NJU8761 is suited for battery-powered applications such as cellular phone and PDA.
