Description :

The NJU8713 is a Switching Driver for a class D Amplifier including Separated Power Source terminals between Input and Output, BEEP and BPZ (Bipolar Zero) output circuits. It converts 1bit digital signal input, such as PWM or PDM signal, to an analog signal output through a simple external LC low-pass filter.

The NJU8713 realizes very high power-efficiency because of the class D operation. Therefore, it is suitable for portable audio set and others.
