NJU8711
DESCRIPTION
The NJU8711 is a Switching Driver for class D Amplifier including BEEP and BPZ (Bipolar Zero) output circuits. It converts 1bit digital signal input, such as PWM or PDM signal, to analog signal output with simple external LC low-pass filter. The NJU8711 realizes very high power-efficiency by class D operation. Therefore, It is suitable for portable audio set and others.
