Description

The NJU8759 is an analog signal input monaural filterless class-D power amplifier. Operating voltage from 1.8V to 5.5V single supply can be used with 2-cell batteries. NJU8759 features Class-D operation with high output capability, is 1.7W output (8Ω load) and 3W output (4Ω load). The BTL output configuration can reduce the coupling capacitor. Furthermore, the output LC filterless architecture, which was not available in conventional class-D, reduces external parts and PCB size. The NJU8759 operates from a single power supply of 1.8 V and 1 µA maximum standby current, and is ideal for small portable devices and portable audio devices, as well as alarm devices and security devices that require low power and high output.

Applications

  • Security equipment
  • Portable Equipment
