The NJU8710 provides powerful drivability in both of sink and source without flow-through current. Therefore, it can be used to the buffer or the switch as a driver IC. Furthermore it converts 1bit digital signal input, such as PWM or PDM signal, to analog signal output of the hi-fi audio level through a simple external LC low-pass filter. The NJU8710 realizes very high power-efficiency because of the class D operation and low voltage operation. Therefore, it is suitable for battery powered applications and others.
