NJU8759A Class-D Amplifier

Nisshinbo Micro Devices' amplifier features Class-D operation with high out put capability

Image of NJR (New Japan Radio) NJU8759A Class-D AmplifierNisshinbo Micro Devices' NJU8759A is an analog signal input monaural filterless Class-D power amplifier. Operating voltage from 1.8 V to 5.5 V single supply can be used with two-cell batteries. NJU8759A features Class-D operation with high output capability and is 1.7 W output at 8 Ω load and 3.0 W output at 4 Ω 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.
