NJU8752/52B NJU3555 www.DataSheet4U.com PRELIMINARY ! PACKAGE OUTLINE Analog Signal Input Class D Amplifier for Piezo Speaker ! GENERAL DESCRIPTION The NJU8752/NJU8752B is an analog signal input monaural class D amplifier for Piezo speaker. The NJU8752/52B includes Inversion operational amplifier input circuit, PWM modulator, an output-short protector and a low voltage detector. Input part operates on 3.3V(TYP) as power supply and Output part operates up to 16.0V(MAX). Therefore, it drives Piezo speaker with louder sound and High efficiency. The NJU8752/52B incorporates BTL amplifier, which eliminate AC coupling capacitors, capable of driving Piezo speaker with simple external LC low-pass filters.
