PRELIMINARY
2V Operation Clock-less Switching Driver for Class D Amplifier
GENERAL DESCRIPTION
The NJU8710 is a 2V operation clock-less switching
driver for a class D Amplifier with separated power supply
between Input and Output.
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.
