NJU8713
2V Operation Switching Driver for Class D Amplifier
GENERAL 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.
