NJU8759
Analog Signal Input Monaural
Filter Less 3.0W Class-D Amplifier
■GENERAL DESCRIPTION
The NJU8759 is an analog signal input monaural filterless
class-D power amplifier. Operating voltage is 1.8V to 5.5V.
The NJU8759 is capable of driving 3W at 5V into 4ohms
without external LC low-pass filters. The NJU8759
incorporates BTL amplifier, which eliminate AC coupling
capacitors. The NJU8759 features high power-efficiency by
class-D operation, and is suited for security equipment,
portable set with speaker, PC, etc.
