CLASS D AMPLIFIER FOR DIGITAL AUDIO
!
GENERAL DESCRIPTION
The
NJU8725
is an 800mW-output class D
Amplifier featuring 6
th
Σ
modulation. It includes
Digital Attenuator, Mute, and De-emphasis circuits. It
converts Digital source input to PWM signal output
which is output PWM signal converted to analog
signal with simple external LC Filter. The
NJU8725
realizes very high power-efficiency by class D
operation. Therefore, it is suitable for battery-powered
applications and others.
