NJU8789
Monaural BTL Output Clock-less Switching Driver for Class D Amplifier
GENERAL DESCRIPTION
The NJU8789 is a monaural BTL output switching driver
for class D amplifier including Separated Power Source
terminals between Input and Output. It converts 1bit
digital signal input, such as PWM or PDM signal.
The NJU8789 realizes very high power-efficiency by
class D operation. Therefore, It is suitable for portable
set with speaker.
