NJU8759A Series
Analog Signal Input Monaural Filter Less 3W Class-D Amplifier
Description
The NJU8759A 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. NJU8759A 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. NJU8759A 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. The NJU8759A is available in an 8-pin HSOP8 package with exposed pads for heat dissipation and a 1.45mm x 1.45mm wafer level package NJU8759WLC1 (see NJU8759 data sheet) for space saving devices.
